Implementing or troubleshooting an ICD-GPS-153 interface can be complex due to its military-specific nature. Here’s a guide to common scenarios and steps:
The protocol is a specialized serial interface standard primarily used in military and high-precision timing applications to facilitate communication between Global Positioning System (GPS) receivers and external devices. What is ICD-GPS-153? icd-gps-153 protocol
While there are dozens of specific messages, these are the core types used in most integrations: Message ID Description While there are dozens of specific messages, these
Military GPS requires precise synchronization. ICD-GPS-153 receivers typically output a separate hardware PPS signal alongside the serial data. The protocol messages include the Time of Week (TOW) aligned to this pulse. supporting military-grade receivers with SAASM security.
ICD-GPS-153 defines the serial communication protocol (RS-232/RS-422) for U.S. Department of Defense GPS User Equipment. It establishes standardized messages for high-accuracy timing and position data, supporting military-grade receivers with SAASM security. Authorized users can request the full specification through the U.S. Coast Guard Navigation Center . GSSIP Message Format - Safran - Navigation & Timing
You cannot find ICD-GPS-153 on a public website. It is (Export Controlled) or higher. You must have a U.S. government contract, a Non-Disclosure Agreement (NDA) with the DoD, and a valid export license (for non-U.S. entities). Request it via the GPS Support Center or your prime contractor.
