Abstract- The National Geospatial-Intelligence Agency ( NGA ) routinely works with commercial and academic spouses to develop and polish engineerings needed to run into the germinating imagery-based intelligence jobs of the intelligence community ( IC ) . There is an bing Research and Development entity within the NGA which includes the systems technology model required to integrate, develop and passage applicable engineerings for usage by analysts. In order to better understand where work may fall within this model, it is necessary to place the built-in proficient adulthood of the research in inquiry. Technology Readiness Levels ( TRLs ) , which were originally developed by NASA and are used by the DOD for most development and procurance plans, are used by NGA as a speedy indicant of both proficient adulthood and built-in hazard ( proficient, agenda, cost or passage ) . This paper discusses the different GEOINT-focused public presentation ratings pertinent to the TRLs so provides a brief debut to an applicable multi-sensor informations merger model.


For a systems applied scientist, the find of a new detector engineering brings about a whole new set of inquiries. Is this a new phenomenology which may supply new penetration into a critical intelligence job? Can this engineering be transitioned into a utile tool? How would this engineering be suitably evaluated while being developed into a tool? Once the tool was in topographic point, what would we make with the ensuing information? This list would go on but it already provides adequate way for this paper. Each of these inquiries will be addressed in one manner or another but the inquiry of what to make with the information is used to develop a model for one method of proficient rating.

The first inquiry to discus is what to make with the new information? Even if the provided information is of critical value that instantly sheds visible radiation on a antecedently unanswerable inquiry, it can still acquire lost in the apparently eternal sum of stored informations and tools. The National Geospatial Intelligence Agency ( NGA ) entirely already investigates several of multiple types of geospatial intelligence ( GEOINT ) detectors ( EO, IR, MSI, HSI, LIDAR, RADAR, Video, etc ) along with those based on signals intelligence ( SIGINT ) and others. As more and more detectors come on line at that place needs to be a method of expeditiously integrating the engineering into an bing substructure in a mode that supports development efficiency. To assist run into this demand, the NGA has established multi-sensor and multi-intelligence ( multi-INT ) informations merger as a top research precedence. Data merger is the chosen application for our new conjectural engineering.

Next, the primary inquiry is that of the rating. With the find of new engineerings comes the demand to properly measure them and their resulting applications. Do we cognize if the detector is adequately modeled or if a new mark acknowledgment algorithm will be effectual in the needed environment? Once this new engineering is added to an bing system, its end product can be fused with the bing informations to assist restrict uncertainness. However, it could besides assist bound effectivity and increase overall undertaking hazard. The general tendency is that as the proficient adulthood of a new thought additions, its related hazard is decreased.The primary index of proficient adulthood used today is the engineering preparedness degree ( TRL ) .

TRL ‘s are frequently a cardinal facet of direction and acquisition for many plans. This is due in portion to their simple representation. One figure provides insight to how long the engineering has been about, how much testing has been performed on it, the hazard to being able to finish a plan based on it, and how much of a cost-impact it may hold on that plan.


When academe publishes a new paper, it may be the concluding consequence of old ages worth of research and supply the foundation for a whole new rule that has been observed but it is still a long manner from being a feasible merchandise. Academia, industry and the authorities demand to hold a sound apprehension of the proficient adulthood of this thought and be able to pass on this apprehension to each other in order to suitably put and farther develop it. It is clear that there would be comparatively low hazard to integrate a engineering that has already reached full proficient adulthood compared to one at TRL 1. Transitioning a new thought to an organisation purpose on immediate merchandise development will probably ensue in agenda holds, cost over tallies and plan cancellation. This is why the overall TRL of a system should non be any higher than the lowest TRL constituent. For case, if an unseasoned projectile engine is to be added to the current infinite bird, it should be clear that important holds or hazard will ensue for the following infinite flight.

Technical preparedness degrees were foremost introduced by NASA in the 1970 ‘s to help in measuring new engineering development. Though different definitions have since evolved between NASA, the DOD and other organisations, most still have the same construction and purpose. TRLs are most normally divided up into 9 separate degrees where TRL 1 indicates a basic principal that has been observed and TRL 9 indicates a concluding merchandise that has been tested and successfully completed existent missions in its intended environment ( see Table I ) .

The definitions of each peculiar TRL degree are reasonably clear ; nevertheless, single readings of the consequences can go less clear. It ‘s non plenty that a undertaking has been tested and evaluated for each degree it really needs to go through an established set of outlooks to go on to the following degree. As a undertaking additions complexness or disbursal there may be an increased inclination to go through work that is of limited quality. This is why it is frequently desirable to hold an independent group behavior these ratings and prove them against a standardised set of demands.

This formal model of proving can assist place unmanageable hazards before excessively much clip and money is spent on development. Besides, the earlier in a undertaking that an unwieldy hazard is identified the cheaper it is to redefine the undertaking in order to extenuate it. If the engineering fails the cogent evidence of concept trial at TRL 3 so there is no point on go oning to the following degree. This could intend that more thought demands to be put into this phase before go oning or that the engineering would be better suited for a different application.

Any new engineering should be tested for each degree from lowest to highest and no degree should be skipped in order to go on the plan. It could be argued that the existent end in the development rhythm is to acquire a undertaking to TRL 6 since this is the point where a to the full incorporate paradigm is successfully tested. The following stage is more refinement and proving in an operational environment which may be out of the custodies of the initial developer. For case, if the undertaking was a UAS ( unmanned aerial system ) capable of blending informations and supplying a sensible situational appraisal to the war combatant, so the paradigm system should at least be flown on an airborne platform. All development is complete one time the system attains TRL 8. TRL 9 indicates the system has successfully completed missions by the intended people in the intended environment. If the system was intended to be portion of a combat vehicle so it may hold to travel though existent missions in a combat theatre in order to make the concluding degree of proficient adulthood.


To assist exemplify the usage and definitions of the TRL degrees a simple fanciful plan will be walked through from origin to concluding merchandise. This merger plan will be utilized to assist take advantage of new detector engineering. Normally, a logical attack would be to maintain the development of a new detector or merger algorithm separate from the development of an overall system but, in this instance, they will be kept together for simpleness.

As mentioned antecedently, there is already a important volume of information for usage by a limited figure of analysts. Even if critical national security information non merely exists but has been collected what are the opportunities that it will do it to the appropriate analyst within a relevant sum of clip? One attack is developing informations merger engineerings to supply two chief maps. First is to dynamically and autonomously fuse information in every bit close to real-time as is necessary. This can be natural detector informations or structured post-processed informations. Second, this fused information demands to analyse so some step of relevancy can be attributed to the information before an analysts of all time sees it. This alert-services attack increases the opportunity that analysts are passing their clip of the most of import informations.


Basic Research ( TRL 1-3 )

It is likely a just premise that most undertakings begin with an thought. At this point a research worker can get down looking into the basic scientific discipline behind the thought to find how much more attempt should be applied to it. In this instance research has determined that a new detector phenomenology may eventually be accomplishable. We know we want to blend the ensuing informations with bing detector informations in a manner that will let for some kind of machine-controlled analysis. Since we are speaking about a new merger procedure or a merger of new informations types and there is no clear, thought out attack, this peculiar merger procedure would be considered TRL 1.

The three largely likely results of a TRL 1 thought are as follows: Determine that it is non worthy of farther development Print a paper on thoughts basic belongingss Continue development to TRL 2

In order to travel to TRL 2 after a formal probe into the usage of the thought has to be thought through. Practical applications and possible constructs of operations are thought out but there is still nil available to turn out that the thought will work.

Once the information is collected and fused, can we find what is on the amalgamate merchandise? Are at that place semisynthetic characteristics that can be pulled out such as roads and pavements or Targets such as armored combat vehicles and aircraft? Once detected, can the Targets be identified? Once these individualities are determined and fused what decisions can be made? Can extra information provide more in-depth analysis or situational appraisal? The construct may besides include a procedure for adding informations from signals intelligence ( SIGINT ) or human aggregation ( HUMINT ) .

So far, the possible application has been broken up into 4 stages: informations merger, feature/target analysis, feature/target designation and conclusions/situational appraisal. These stages are similar to the JDL revised informations merger theoretical account. [ twenty ]

JDL Functional Data Fusion

Application Phases

informations merger

  • Entity appraisal
  • mark analysis

  • Situation Appraisal
  • mark designation

  • Impact Assessment
  • decision

  • Procedure Appraisal

Once the functional appraisal is thought through it may be possible to get down identifying needed constituents to run into specific demands. Insight may besides be found for the constituents required public presentation, size, form and even power demands. A simple model for criterions and trial programs can be thought through. Once the application is sound and a construct begins to develop so the engineering may be considered TRL 2.

After active R & A ; D on the rule engineering is initiated and some signifier of relevant testing is completed the thought is a cogent evidence of construct and can be considered TRL 3. This is the first degree of existent testing and can include the running of an algorithm or research lab consequences every bit long as it validates a cardinal portion of the engineering. Multiple trials may be conducted on different, stray, non- representative constituents of the system entirely to verify feasibleness of single engineerings. ( show that false dismay rate is non inordinate )

Testing is complete one time its shown single parts can make their required occupations. Other possible consequences include technology codification, schematics, and high degree demands.

Now that the thought behind the engineering has been tested, hazard has been reduced plenty more serious ideas into commercial/government applications. From this point you can

Determine if the engineering is mature plenty

Verify that there is a demand for the application

Refine construct

See alternate utilizations of the engineering

Develop constituent integrating scheme

Refine system functionality and public presentation demands

Develop a roadmap to a deliverable or TRL 7 system

Technology development ( TRL 4-5 )

To be evaluated for TRL 4, the merger algorithm is incorporated into package and other low fidelity package and hardware constituents are integrated. This is the first clip single constituents of the application are set to work together. This shows that the constituents can work together and allows for the first degree of true map confirmation.

This package will probably be really crude and awkward but the purpose is non to hold a marketable solution, merely to be traveling in that way. In fact, several different paradigms may be needed in order to verify different trial instances.

The following degree of proficient adulthood requires that the constituents be tested in a relevant environment. This may still be in the original development research lab environment but with the system utilizing existent informations or interacting with existent libraries or communicating systems. Connections to other systems should be simulated to assist verify system integrating. The relevant environment may besides bespeak the usage of realistic jobs. Once at TRL 5, this is the degree where the engineering is ready for integrating into bing systems.

System Development ( TRL 6-7 )

TRL 6 is where the engineering feasibleness is to the full demonstrated. Alternatively of single constituents being evaluated, the system paradigm is to the full developed with all constituents working together. This is besides where it is connected to bing systems and run on all-out realistic jobs in a fake operational environment. This demonstrates signifier, tantrum, map and validates all system demands. User and preparation manuals could be finalized at this province. The staying three degrees of proficient adulthood merely affect the development of the concluding system from the now complete paradigm and usage in the operational environment.

After the paradigm is successfully working together and evaluated so undergoes further development and brought into the coveted environment for proving and rating. This system in near to being the planned operational system. Depending on the concluding construct for the application, this is where the system would be moved into operations or flown on a bed aircraft. The applications mission operational value confirmed. Before continuing to concluding system development, all interest holders should be involved and concur that everything is runing as expected.

System Test and Operation ( TRL 8-9 )

The system is farther developed in built into its concluding signifier which is so tested and demonstrated. Once the deliverable quality system is produced and tested it is considered TRL 8 existent development is completed.

The concluding TRL is achieved when the full version system is operational in the operational environment and successfully completes full missions.
