Exhibit 1. Narrative Statement Describing The Government Contract MITRE Corporation is developing a prototype Satellite Communications (SATCOM) On The Move (SOTM) terminal designed to operate at Ku—band. The MITRE effort is being sponsored by the US Army Program Executive Office for Command, Communications, and Control Systems (PEOC3S), Fort Monmouth, NJ. This program is intended to develop a prototype terminal mounted on a High Mobility Multipurpose Wheeled Vehicle (HMMWV) that will be subjected to various unimproved road conditions to characterize the terminal‘s ability to faithfully track the satellite under extreme conditions. The prototype terminal employs commercial off—the—self (COTS) equipment designed for Ku—band SATCOM operation. To mitigate the risk of interference, the terminal makes use of a direct sequence spread spectrum modem.

Exhibit 2. Narrative Statement Describing The Research Project Medium Data Rate Satellite Communications (SATCOM) On The Move (SOTM) for the Battalion—Level Warfighter This Army—sponsored Mission Oriented Investigation and Experimentation (MOIE) calls for the design and prototyping of an affordable satellite communications (SATCOM) terminal that can support SATCOM OTM (SOTM) and Medium Data Rate (MDR) SATCOM On—The—Pause (SOTP) communications. The anticipated data rate required for SOTM operation is 128 kbps. This program is intended to develop a prototype terminal mounted on a High Mobility Multipurpose Wheeled Vehicle (HMMWV) that will be subjected to various unimproved road conditions to characterize the terminal‘s ability to faithfully track the satellite under extreme conditions. Under the MOIE program, research is underway in four key challenge areas; development of a low—cost platform stabilization and antenna tracking system; development of a link layer protocol to support shared channel access; conduct waveform performance analysis using RF channel simulator to tune modem hardware; and develop a small aperture antenna with excellent gain and low sidelobes. The prototype terminal will represent the successful integration of our research with low cost COTS products to support SOTM. The HMMWV—mounted prototype terminal will undergo test and characterization that will lead to FCC certification. The resulting prototype terminal will serve as a mobile lab to enable MITRE to refine the performance (e.g., data rate, road challenges, communications reliability) of the terminal. We plan to conduct a series of demonstrations that confirm the prototype terminal‘s ability to exchange SA and some C2 messages OTM. In addition, a requirements specification will be developed to assist the Army program office in defining a program for the procurement of SOTM terminals. Low—cost platform stabilization will be achieved by leveraging the use of Fiber Optic Gyros (FOGs) as a key part of the tracking system. The tracking system will be a hybrid design, which includes open loop tracking with periodic closed loop updates to correct for drifting of the inertial system. The link layer protocol will support reliable, shared and efficient satellite transponder channel access. The link layer protocol will be designed to service both multicast and unicast routed messages. Furthermore, the protocol will support peer—to—peer and hub— spoke connectivity and minimize the mobile SATCOM terminal‘s modem count.
