TW5310 GPS Smart Antenna/Receiver
The TW5310 by Tallysman Wireless is a professional grade integrated GPS smart antenna/receiver.
It features the STMicroelectronics STA8058 Teseo™ WAAS, EGNOS and MSAS enabled GPS L1 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.
The TW5310 is housed in an industrial grade weatherproof IP67 enclosure for 19mm diameter (¾”) thru-hole mount or mast mount installations and comes with NMEA 0183 standard output via a RS232 interface.
