TW5115 GPS Embedded Smart Antenna/Receiver

The TW5115 by Tallysman Wireless is a professional grade embedded GPS smart antenna/receiver.

It features the STMicroelectronics STA8058 TeseoTM WAAS, EGNOS and MSAS enabled GPS L1 receiver IC, a high performance low noise amplifier stage, a tight out-of-band BAR pre-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.

The TW5115 comes in a very compact, low profile (7.6mm) form factor, with a NMEA 0183 standard output and RS232 and CMOS interface. A very low profile form factor (5.6mm) is available on request.
