Icd-gps-153 Protocol File

The ICD-GPS-153 protocol, also known as the Interface Control Document for GPS 153, is a technical standard for communication between GPS devices and external equipment. The protocol defines the requirements for data exchange between GPS receivers and devices such as computers, autopilots, and other navigation systems.

: It was built to interface seamlessly with classic military hardware like the PLGR (Precision Lightweight GPS Receiver) and its successor, the DAGR (Defense Advanced GPS Receiver) .

“Ensign,” Vahn said, her tone sharp as a scalpel. “You decoupled your local inertial reference from the fleet network. You are running an independent GPS solution.”

: It is designed to work with military security architectures, supporting the exchange of encrypted and protected navigation data. Dual Frequency Support : The protocol handles data from both carrier frequencies, including C/A, P, and encrypted P(Y) codes Physical Interface : Typically implemented over (RS-232) serial connections.

Military GPS relies on Selective Availability Anti-Spoofing Modules (SAASM) and modern M-Code receivers to prevent signal jamming and spoofing. ICD-GPS-153 provides the exact messaging interface required to: Load and zeroize cryptographic keys (Black and Red keys). Monitor security architecture status.

Frequently used to provide precision time transfer (1PPS) and frequency control to networked systems. Common Message Types Ensure the request is signed by an authorized

The protocol is often implemented in specialized software libraries (like

The ICD-GPS-153 protocol is a binary protocol that allows a GPS receiver to transmit GPS data to a host device, such as a computer, microcontroller, or other electronic device. The protocol defines the format and structure of the data transmitted between the GPS receiver and the host device, ensuring that both devices can communicate effectively and accurately.
