1 Technical Supplement For Joint Standard Instrumentation Suite Missile Attitude Subsystem (JMAS) 1. INTRODUCTION Version Scope This Technical Supplement describes the Government s need for a capability to provide 6 Degrees of Freedom (6DOF) attitude data (absolute X,Y,Z position, pitch angle, yaw angle, roll) of a Man-portable air defense system (MANPADS) or track mounted infrared (IR) guided missile while in flight from launch point to a stationary target point against the natural test area background. This need also includes the corresponding pitch angle and yaw angle of the missile plume. 1.2 Background MANPADS employing infrared seekers are the single biggest threat facing slow-moving, low-flying rotary wing and fixed wing platforms. To counter the prevalent MANPADS and related track mounted IR guided missile threat, the Services are developing autonomous infrared countermeasure (IRCM) systems for installation on several helicopters platforms as well as large aircraft platforms. Ground truth data are needed to improve the modeling and simulation of MANPADS and other threats missile attitude being the most critical data need. 1.3 Demonstration The selected vendor will be required to conduct a demonstration of their prototype, prior to each delivery in incremental capability, in a field environment to enable an assessment of progress toward achieving the required capability. The specific objectives of each demonstration will be established jointly by the vendor and Government team. The objectives of the demonstrations will focus on basic system performance to include: gimbal performance, optical subsystem performance, and scintillation mitigation. 2. TECHNICAL REQUIREMENTS AND OBJECTIVES Certain requirements are specified in terms of minimum and goal values where: a) Minimum - Level of performance that is considered achievable at low-to-moderate risk. b) Goal - Level of performance which is the ultimate, desired operational goal. 2.1 Technical User Interface The interface between the system and the user must include a Graphical User Interface 1

2 (GUI) which allows the user to perform any and all functions necessary to meet the performance requirements of this document. Features that minimize duplicative operator input are highly desired. Storage The system should have the capability to store all shots for a typical event with a reserve capacity of 100%. A typical event is defined as 75 shots with an average shot duration of 15 s [minimum] / 30 s [goal] at the maximum sample rate (where shot duration is defined as 200 ms prior to first light plus 9.8 s). Operator access to system storage media should not require mechanical disassembly. Remote Communications The system should provide a network link over which an operator can monitor and control remote system elements from a system operator station installed within a Government control van. System log The system should include a logging capability to include, at a minimum: System software configuration System hardware configuration Shot designator Log entry time stamp Built-in-Test (BIT) The system should have BIT capabilities to identify problem areas or non-working equipment that requires removing and replacing prior to the start of data collection or during routine maintenance. All BIT messages should be electronically and automatically recorded and logged for future use and diagnostics and should be displayed to the operator. System health, Status and Configuration Monitoring The system should include a function that reports system health, status and configuration monitoring to the operator. Missile Trajectory Coverage The system should provide a solution of the flight position and attitude of single launches of MANPADS missiles while in flight from launch point (0 m downrange) to a stationary target point against the natural test area background. The Missile Trajectory Coverage performance requirements of the system are summarized in Table 1. 2

System Trajectory Coverage Requirements Requirement Requirement Minimum Goal Number Downrange trajectory coverage 3500 m 7000 m Cross range trajectory coverage +/- 500 m +/ m Altitude trajectory coverage (above ground level) 0 m to 2000 m 0 m to 5000 m Measurement Accuracy Reduced measurement outputs from the system consist of an attitude solution of the missile hard body (5DOF [minimum] and 6DOF [goal]) as well as the pitch angle and yaw angle of the missile exhaust plume for the MANPADS trajectory. The system analysis results will be measured against the accuracy requirements in Table 2. Table 2. System Trajectory Measurement Accuracy Requirements Requirement Requirement Minimum Goal Number Absolute missile +/- 2 m +/- 0.5 m position accuracy Missile Yaw Accuracy +/- 1 +/ Missile Pitch accuracy +/- 1 +/ Roll rate n/a +/- 2 hz within max rotation rate of 20 Hz Roll Position n/a +/ Missile exhaust plume pitch and yaw +/- 2 +/- 1 Sample Rate The system should have the capability to measure/sample and record missile data at 100 Hz [minimum] and 500 Hz [goal]). Data should be recorded with associated time tag values (accurate to 1 ms or better). Relevant test metadata should also be recorded at no less than 1 Hz with associated time tag values of the same accuracy. Data Products The system should include data products which include interim and final missile attitude data as well as operator quick look reports that summarize JMAS data collection status for each missile shot. The system should include a mission planning tool to help determine optimum placement of instruments during system setup based upon user input of event details such 3

System Operating Environment The system should support operations in the following lighting conditions: Daytime natural light (between 1 hour after sunrise and 1 hour before sunset) [minimum] to all natural lighting conditions (including dark) [goal] The system should be designed to operate with externally provided shore or generator power of VAC 50/60 Hz and 208VAC 3-phase The system should be capable of operating in an ambient temperature range of 10 F to 125 F The system should be designed to operate in an ambient humidity conditions of 1% to 95% non-condensing The system will not be operated in the rain or snow The system should operate and meet the stated accuracy specifications under the scintillation conditions of 2.0e -14 [minimum] / 1.0e [goal], characterized by C n (meters 2 3) 2 where C n is the refractive index structure parameter (see non-government reference documents) The system should meet missile attitude accuracy requirements when operated in sustained wind conditions of up to 20 kts and gusts of up to 35 kts. System External Interfaces Acquisition Trigger The system should provide the means to accept an external software trigger indicating the projected event time (i.e., MANPADS launch). The system design should be such that data for the entire 15s [minimum] / 30s [goal] MANPADS launch is captured and recorded External Time Standard Interface The system should accept an external time synchronization signal in the form of both analog and digital IRIG B Test and Training Enabling Architecture (TENA) The system should provide a TENA interface to enable interoperability with other TENA enabled systems. Security 4

5 Classified Data Processing The system should have: a) The capability to collect and process data at the levels of both Sensitive but Unclassified (SBU) and SECRET Collateral (S-C). b) The means to operate in a secure mode for collecting classified data and to restore the system to its unclassified configuration Cyber Security JMAS will be operated on DOD ranges so the system should be designed to minimize risks to system operations and data from cyber threats consistent with National Security Telecommunications and Information Systems Security Policy (NSTISSP) No. 11 and DOD Instruction , Cybersecurity. The contractor should design this system consistent with the cybersecurity provisions of the JSIS System Security Plan (SSP) and support the Government in revisions to this SSP and related documents, where necessary, to reflect integration of JMAS into the technical baseline. Transportability and Setup The system should be a self-contained, missile attitude capability that is capable of being deployed at remote test ranges both within the Continental United States (CONUS) (e.g., Dugway Proving Ground, White Sands Missile Range, and Tonopah Test Range) and Outside the Continental United States (OCONUS) via best mode to include commercial air freight. No special permits should be required for CONUS ground shipment of the system. This will generally limit the payload to 13 6 in height, 8 in width, and 53 in length when installed on a commercial trailer (inclusive of any enclosures). 2.2 Program Management The Contractor should accomplish all planning, execution, monitoring and controlling, reporting and related program management activities to ensure that the technical, schedule, and financial requirements of this contract are accomplished. Program Management documentation should include periodic technical, financial, and schedule status. Communication The contractor should establish and maintain regular communication with the Government team (both formal and informal) so that plan deviations are known, assessed, and resolved in a timely manner. This communication should include contractor participation in informal bi-weekly status meeting phone calls with the Government during which the contractor should cover the technical and programmatic status of the project. Reviews The contractor should host and conduct periodic reviews throughout the requirements analysis, design formulation, risk reduction, and test phases of the contract consistent with best commercial practices. The contractor should summarize the review contents and action items and submit to the Government on an IPT-determined basis. 5
