Introduction
The TW5310 is an integrated GPS receiver/antennas designed for use in professional
grade applications such as vehicle tracking and timing applications.
It features the STMicroelectronics STA8058 Teseo™ WAAS, EGNOS and MSAS enabled
GPS receiver IC, a high performance low noise amplifier stage, a tight out-of-band SAW
filter to reject interference, and a perfectly tuned antenna element for maximum GPS
signal reception, even in dense urban-canyon environments where multipath
interference is prevalent.
Available with brick-wall filter option to eliminate possible interference from
Lightsquared transmissions.

The TW5310 is a through-hole mount GPS receiver/antenna housed in an industrial
grade weatherproof IP67 enclosure. It provides NMEA 0183 standard output at
RS232 levels.
Differential 1 pulse-per-second (1PPS) outputs are provided at RS422 levels. The
1PPS is synchronized to UTC.
A GPS position fix is obtained in less than 39 seconds from a cold start, and recovery
from temporary blockage of GPS signal is typically less than 1 second.
The last known position is periodically written to non-volatile memory to maintain
position information across power cycles.
