UT-41R-RS232 GPS Receiver

Description

With a miniature form factor, the UT-41R-RS232 GPS Receiver module utilises 12-channel GPS technology and is designed for rapid startup time and high performance in foliage and urban canyon environments. The UT-41R-RS232 applies the latest semiconductor technology so as to provide robust performance, enhanced position & velocity filtering for smooth navigation, onboard patch antenna & RS-232 driver for simple interfacing.

The UT-41R is optimised for applications requiring good performance, low cost and maximum flexibility. It is suitable for a wide range of applications including asset tracking and monitoring. Satellite-based augmentation systems (SBAS) such as EGNOS and WAAS are supported to yield improved accuracy.
