These precision timing systems can emulate an ICD-GPS-153C compatible SAASM GPS without a SAASM receiver. They generate the three core messages, sending time and 1PPS signals to external SINCGARS-compatible devices. Position and velocity information is zeroed out, but the timing data is accurate and emulates the interface flawlessly. icd-gps-153 protocol

This protocol's main role is to distribute PNT data while ensuring against increasingly common threats like jamming and spoofing in modern electronic warfare. Its power lies in how it marries secure hardware with a well-defined data structure, enabling legacy systems to be upgraded with modern capabilities. Position and velocity information is zeroed out, but
: A standardized numerical code identifying the packet's contents (e.g., position, time, or status).
The protocol defined the "Standard Serial Data Interface for GPS Receivers." Technically, it wasn't just a data format; it was a hardware handshake.
