JPO certs L-3 GPS. (Digest).

The GPS Joint Program Office (JPO) has certified L-3 Communications/Interstate Electronics' (IEC) compliance with design and review security requirements set forth by the US Department of Defense, thereby clearing the way for L-3 to proceed with the production of its Saasm-based GPS receiver (Saasm module pictured at right). The GPS JPO is responsible for the control, development, production, sale and distribution of GPS security devices within the United States. IEC's classified system incorporates three functions, which include selective availability, anti-spoofing and the associated cryptograph, all which are required under the Global Positioning System Precise Positioning Service (PPS) requirements. The GPS unit includes the required PPS security module, an Auxiliary Output Chip (AOC), a combined PPS/AOC device, the Selective Availability Anti-Spoofing Module (Saasm) and a Saasm code block device. To protect the unit's security functions, IEC has incorporated hardware and software security devices that prevent unauthorised access or tampering.
