Icd-gps-153 Protocol

Devices like the Safran NetClock use ICD-GPS-153 messages to provide 1PPS (pulse-per-second) and time-of-day information to external equipment without requiring a full military-grade receiver for simple time-only tasks.

Here is why ICD-GPS-153 matters, and why its ghost still haunts modern receivers. icd-gps-153 protocol

(Interface Control Document - GPS - 153) is a specialized communication protocol primarily used for interfacing Department of Defense (DoD) standard GPS receivers with host platforms via RS-232 or RS-422 serial interfaces. It is the standard protocol for military-grade receivers like the Defense Advanced GPS Receiver (DAGR) and older Precision Lightweight GPS Receivers (PLGR) .
