1. Introduction to GPS L70 Easy
The L70 is a GPS module from Quectel. The L70 is designed with MTK's MT3339 GPS core chip, which has excellent GPS reception capabilities. "66 accquisition channels - 22 tracking channels". Distance error less than 10 meters, more precisely the chips are used as Ublox, Holux ... The highlight of the L70 module is the low current consumption of only 22-25mA and very small size only 10.1x9.7x2 .5mm.
GPS L70 Easy is a product developed by AT-COM based on the features of the L70 Module . GPS L70 Easy is designed to be a compact, an easy-to-navigate device that allows users to easily research and deploy related applications to GPS such as positioning the map on a Google map, measuring speed, and time...with high precision. In addition, with compact size, handy data output, GPS L70 Easy will deliver the most modern and sophisticated design inspiration.
GPS L70 Easy was designed by AT-COM with 2 versions selected using External Antenna and Internal Antenna.
Version 1: Use the RF connector to connect the External Active Antenna GPS.
This version uses 1 RF Connector to connect to the external antenna. The connector is suitable for the outer sheathing of the product and uses antennas that extend 3 to 5 meters.
The circuit is tested with 3-meter Extenal Active Antenna GPS of Jinchang with 28 dB gain, 2.2-5V operation power, 5-15mA current consumption, good GPS tracking and main return coordinates. The error is less than 10 meters.
With this version is suitable for GPS applications deployed environment outside, it is resistant rain, sun and high temperatures such as vehicle positioning equipment, taxi, ship ...
Version 2: uses Internal Active Antenna GPS welded on the circuit
This version is designed to weld Internal Active Antenna GPS onto the circuit without using an external antenna, making the circuit very compact and suitable for small design and space saving.
The circuit is tested with Internal Active Antenna GPS of Jinchang with 28 dB gain for good GPS reception and GPS accuracy returns accuracy less than 10 meters.
With this version suitable for applications in the research environment, applications in the less harsh environment.
