If you work in GNSS, aviation, or embedded systems, you’ve likely heard of ICD-GPS-153. But if you haven't, you’re missing out on one of the most fascinating "missing links" in GPS history.
The ICD-GPS-153 (Interface Control Document for the RS-232/RS-422 Interface of DoD Standard GPS User Equipment) is a critical technical standard that defines how military Global Positioning System (GPS) receivers communicate with host platforms. Unlike the consumer-grade NMEA 0183 protocol common in civilian devices, ICD-GPS-153 is designed for the rigorous demands of Department of Defense (DoD) hardware.

Often referred to as the GPS Standard Serial Interface Protocol (GSSIP), it ensures interoperability between military receivers (such as the Defense Advanced GPS Receiver - DAGR or PLGR) and host vehicle systems or mission computers.
