Icd-gps-153 Protocol !!exclusive!! Jun 2026

Unlike civilian protocols that are open and unencrypted, ICD-GPS-153 is designed to support:

ICD-GPS-153 defines the . It specifies the message formats, data structures, and timing requirements for serial communication over RS-232 or RS-422 ports, commonly used in defense applications.

) can be swapped or integrated into various platforms like missiles, aircraft, or handheld devices. Mayflower Communications message formats or how it differs from commercial protocols like NavGuard® 100 SAASM GPS Receiver with Anti-Jam icd-gps-153 protocol

The protocol ensures the 1 Pulse Per Second (1 PPS) signal aligns perfectly with the time information in the binary messages.

: Frequently used in tactical sensors like the VectorNav VN-210 to interface with external military GPS units. Standard Message Examples

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. Unlike civilian protocols that are open and unencrypted,

The ICD-GPS-153 messages are sent using the GPS Standard Serial Interface Protocol (GSSIP). This three-message set is specifically designed to emulate the communication link between a SAASM GPS receiver and a SINCGARS radio system. An external device can listen to these serial messages and receive time and 1PPS signals as if it were connected to a secure military GPS source. For many simulation and test systems, these messages can be emulated, meaning no actual SAASM receiver hardware is required to generate the timing data for a SINCGARS interface. In such emulation cases, position and velocity data are often zeroed out, and only timing information is provided.

Provides raw measurement data. Status Messages: Channel, satellite, and SAASM status. Time Mark (8504): Supports precision timing data.

In practical terms, defines the electrical, functional, and protocol characteristics required for a host system (e.g., a fighter jet’s mission computer, a ground vehicle’s battle management system, or an artillery fire control unit) to communicate with a precision military GPS receiver . : Frequently used in tactical sensors like the

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.

Sent at a lower frequency (typically once every 6 seconds or 1/6 Hz), this is used for broader system health and data buffering. Major Applications

For authorized users—primarily the U.S. military, allied forces, and select government agencies—the gateway to this encrypted, anti-spoofing, anti-jamming world is defined by a restricted document: .
