[[File:ICE-GPS-r1.2-top.jpg|thumb]] [[File:ICE-GPS-r1.2-bottom.jpg|thumb]]
The ICE-GPS is a GPS-driven, mixed-signal phase-lock loop, providing a 1 PPS output, an IRIG-B output, and generating a 10MHz sine output from an extremely low jitter voltage-controlled crystal oscillator (VCXO). The 10MHz output is disciplined from an onboard GPS receiver, which drives the long-term frequency stability. The onboard GPS receiver at the core of the ICE-GPS is the Conner Winfield CW25 timing receiver.

The board is formatted as an ICE I/O module for use with the [[ICE-PIC6]], [[ICE-POD]], or [[ICE-PAC]]. The antenna input is available on an SMA connector and will operate an active antenna at 5V. The 10MHz, 1PPS, and IRIG-B are available on SMB connectors, each able to drive four 50 ohm loads.

The ICE-GPS communicates to the host computer through the base ICE card using C-callable library functions. These calls allow access to all NMEA/TSIP protocol information made available by the CW25 module. The user can observe the status of the unit, time of day, position, and current satellite quality/configuration information via either of the two protocols.
