LS2003C-G GNSS EVK Module - Smart Antenna for Accurate Navigation

LS2003C-G GNSS EVK Module – Smart Antenna for Accurate Navigation

LOCOSYS LS2003C-G is a standalone GNSS module with a smart antenna that integrates patch antennas and a GNSS receiver. This module supports simultaneous reception and tracking of several satellite systems, including GPS, GLONASS, GALILEO, QZSS, and SBAS. With low power consumption and a compact design, it is suitable for various devices, including mobile applications with high demands for sensitivity and performance.

The LS2003C-G module achieves a fast cold start thanks to hybrid ephemeris support. The implemented EASY system auto-generates ephemeris predictions without the need for network connectivity, enabling efficient operation for up to 3 days. Server-generated ephemeris prediction (EPO) ensures validity for up to 14 days. Both predictions are stored in onboard flash memory, and the cold start time is less than 15 seconds.

Installation of the module is very simple, as it does not require RF connectors and coaxial cables. This reduces manufacturing costs and device size, speeding up time to market. The module can be powered directly by a lithium battery without the need for an external voltage regulator. This makes it ideal for integration into compact devices due to its attractive form factor and high performance.
