GPS Joint Program Office Grants L-3 Communications /Interstate Electronics Final Security Approval of their SAASM-based GPS Receiver

IEC is the first SAASM manufacturer to demonstrate compliance with all new requirements in the SAASM design

ANAHEIM, CA, – July 17, 2002 - Interstate Electronics Corporation (IEC), a wholly owned subsidiary of L-3 Communications Corporation, announced their Selective Availability Anti-Spoofing Module (SAASM)-based Global Positioning System (GPS) receivers; X-Factor SAASM and TruTrak Projectiles, ERGM and XM982 GPS Receivers successfully completed a security review by the GPS Joint Program Office (JPO). IEC is the first SAASM manufacturer to demonstrate compliance with all new features inherent in the SAASM design. The GPS JPO ensures compliance of GPS security requirements set forth by the U.S. Department of Defense.

The GPS JPO is responsible for controlling the development, production, sale and distribution of GPS security devices. IEC's classified system incorporates three functions: selective availability (SA), anti-spoofing (A-S), and cryptography, which are required for achieving Global Positioning System Precise Positioning Service (PPS) capability. IEC's GPS unit also includes the required Selective Availability Anti-Spoofing Module (SAASM), a state-of-the-art electronic design utilizing the JPO and NSA approved Key Data Processor (KDP) II devices, and IEC's proprietary SAASM Code Block (SCB), all protected with tamper resistant coating. This coating, along with hardware and software embedded in the SAASM, helps to protect the GPS PPS security functions from unauthorized access or tampering, due to theft or loss of the unit.

"The JPO was very impressed with the SAASM Extended Function test results that IEC was able to demonstrate with our Projectile SAASM GPS Receiver and our Model 2450 Satellite Constellation Simulator, (SCS), that was upgraded to execute the GPS JPO’s SAASM Test Vectors," stated Paul Bricker, director of GPS Programs. "The JPO said that this was ‘a milestone event in SAASM history’ since IEC was the first manufacturer to demonstrate compliance with all the new features inherent in the SAASM design."

 Editor’s Notes:

The SAASM assembly is a MultiChip Module (MCM) which contains the core logic devices for a P (Y) code GPS receiver. The SAASM along with RF down converter and I/O logic, forms the complete GPS receiver. The small form factor GPS design must survive gun shot acceleration forces exceeding 15,500Gs while maintaining exact performance requirements including precision timing to within 10 microseconds.
