12 Channel GPS Sensor Module

The GPS-41BTM is a single board of Bluetooth-GPS module solution for customers who require easy system integration and minimal development risk. The GPS-41BTM is optimized for good performance and low cost. Its 12 parallel channels and 4000 search bins provide short start-up time and fast signal acquisition. Having fast time-to-first-fix and enhanced sensitivity, the GPS-41BTM offers good navigation performance even in urban canyons. Satellite-based augmentation systems, such as WAAS and EGNOS, are supported to yield improved accuracy. The onboard patch antenna provid es good signal reception. In situations where the GPS-41BTM is integrated into an application where the patch ant enna has limited view of the sky, external active antenna may be directly connected via the MMCX connector to provide improved signal reception. Class 2 Bluetooth offers up to 10 meters of wireless operation with Bluetooth-enabled devices such as PDA, Tablet-PC or Smart mobile phones.

When the 5V DC source is connected to charge the Li-I ON battery, the green charging-battery LED indicator will turn ON. The battery will be charging at 48mA duri ng the pre-charge phase until 2.93V is reached. Next, charge current changes to 480mA during the full-charge phase until 4.1V is reached. Afterwards, charge current will decrease gradually until 48mA is reached, and the charge current will fall to a very low value and remain in the trickle charge phase. The green charging-battery LED indicator remains ON until the 5V DC source is disconnected. MEA Messages The serial interface protocol is based on the National Marine Electronics Association’s NMEA 0183 ASCII interface specification. This standard is fully define in “NMEA 0183, Version 3.01” The standard may be obtained from NMEA, www.nmea.org GGA - GPS FIX DATA Time, position and position-fix related data (number of satellites in use, HDOP , etc.).
