G12 Sensor  The Ashtech G12 GPS
Sensor sets a new standard for unsurpassed performance in a wide assortment of
high-accuracy marine, avionics and land navigation applications. This powerful 12-channel
receiver is the first of its kind to offer a 20Hz update rate option for real-time
guidance, position and raw data output. The G12 offers differential accuracy of less than
40cm, position latency better than 50ms, and exact position latency to millisecond
accuracy. It delivers precise three-dimensional positions to meet the demanding
requirements of high-end OEM system integration. The G12 Sensor comes enclosed in a
rugged extruded aluminum housing for convenient integration into a wide variety of
applications, and can be ordered in "base station" or "roving
receiver" configurations.
The G12 Sensor incorporates
all-in-view tracking to track up to 12 satellites with a "loss of lock"
re-acquisition time of less than 2 seconds, and delivers unsurpassed position accuracies
of better than 40cm achieved immediately following satellite acquisition. Signal
inaccuracies are removed with RAIM (Receiver Autonomous Integrity Monitoring), and
Ashtech's revolutionary new strobe correlator technology provides unmatched multipath
mitigation for code, providing the best possible position accuracy.
The G12 Sensor also offers distinct
timing options for precise timing and frequency, or time-tagging of positions, including
1PPS time pulse, variable frequency output, an event marker to tag time a position, and a
programmable measurement strobe that generates a pulse at a programmable interval in
advance of measurements.
Ashtech Evaluate software is
available with the G12 Sensor and provides visual displays of satellite information (e.g.,
SNR), receiver position and velocity, as well as data logging and analysis. It also allows
direct communication with the receiver. Compatible with both the G12 and the Sensor II
boards, the software runs on Windows® version 3.x and Windows '95 platforms.
The G12 Sensor System, which
includes the G12 Sensor, antenna, reference manuals, and all necessary cables, enables you
to get started right away. Add Ashtech's Evaluate software, and you've got everything you
need to perform a comprehinsive G12 Sensor test-drive!
Also available is the G12 OEM Board,
ready for integration into your high accuracy GPS application. See our
"Receiver Boards and Kits" section for more information.
