LS2003D-G

The LOCOSYS LS2003D-G is a complete standalone GNSS smart antenna module with embedded patch antenna and GNSS receiver circuits. The module can simultaneously acquire and track multiple satellite constellations that include

• GPS
• GLONASS
• GALILEO
• QZSS
• SBAS

The module draws low power and is packaged in a small form factor. Ideal for providing superior sensitivity and performance in urban areas and dense foliage environments.

This module supports hybrid ephemeris prediction to achieve a faster cold start. Self-generated ephemeris prediction (called EASY) requires no network assistance or host CPU intervention. This is valid for up to 3 days and updates automatically from time to time when the GNSS module is powered on and satellites are available.

A server-generated ephemeris prediction (called EPO) is achieved from an internet server. This is valid for up to 14 days. Both ephemeris predictions are stored in the on-board flash memory and perform a cold start time in less than 15 seconds.

The module is easy to install without both RF connector and coaxial cable that are needed in a separate GNSS active antenna. Reduce cost and size, this also helps to speed up the time to market by eliminating R&D efforts on RF matching and stability between separate GNSS antennas and modules.

The LS2003D-G can be directly powered by a lithium battery without any external voltage regulators. Its miniature size and brilliant performance make it an ideal choice for integration into modern slim devices.
