Icd-gps-153 | Protocol

If you need access to the actual document, contact your DoD program office and request a (Military Critical Technical Data Agreement). Without that form, ICD-GPS-153 will remain a closed book—by design.

Military vehicle GPS units, such as those from SITEP Italia , utilize the protocol to integrate with on-board computers.

Delivers high-precision time data synced alongside a hardware 1 PPS (Pulse Per Second) strobe. 1/6 Hz (Once every 6 seconds)

The ICD-GPS-153 protocol has numerous applications in various fields, including: icd-gps-153 protocol

| | Primary Use Case | Key Characteristics | | :--- | :--- | :--- | | ICD-GPS-153 | Military GPS Receivers | Secure, SAASM-compatible, deterministic binary/ASCII messages for PNT and status data | | NMEA 0183 | Civilian Maritime & GPS | Text-based, sentence-oriented, less secure, limited data types | | STANAG | NATO Military Systems | Broader standard encompassing multiple PNT and radio interfaces, ensuring NATO interoperability | | ICD-GPS-060 | Military GPS Receivers | Older standard; succeeded by ICD-GPS-153 for many modern applications |

The protocol includes a specific "GSSIP" (GPS Standard Serial Interface Protocol) format often used to emulate military interfaces like SINCGARS : : Sent at 1 Hz. Time Transfer : Sent at 1 Hz for precise synchronization. Buffer Box : Sent every 6 seconds (1/6 Hz). Access and Compliance

Transmitted at 1/6 Hz; used for legacy compatibility with SINCGARS (Single Channel Ground and Airborne Radio System) interfaces. 3. Protocol Applications Military Integration: If you need access to the actual document,

Are you integrating a specific military receiver like a or NavAssure unit into your system? VN-210 GNSS/INS: User Manual - Metromatics

The hallmark of the 153 protocol is . The Y-code cannot be generated without the current W-key (part of the GPS Week Number and time-of-day). This means:

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. Buffer Box : Sent every 6 seconds (1/6 Hz)

ICD-GPS-153 is extensively used in environments requiring high reliability and security.

In electronic warfare, positioning data is a high-value target. The ICD-GPS-153 protocol sits between the GPS core engine and the system using that data (the host vehicle, weapon system, or tactical network).
