Sub-meter Smart Antenna Module
LS2003H-Vx series products are high-performance dual-band GNSS smart antenna modules, including an embedded antenna and GNSS receiver circuits, designed for a broad spectrum of OEM system applications. The GNSS smart antenna will acquire both L1 and L5 signals at a time while providing the better standalone position accuracy. It can provide you with fast Time-To-First-Fix, superior sensitivity and low power consumption.
The modules support hybrid ephemeris prediction to achieve faster cold start. One is self-generated ephemeris prediction (called EASY) that is no need of both network assistance and host CPU's intervention. This is valid for up to 3 days and updates automatically from time to time when GNSS module is powered on and satellites are available. The other is server-generated ephemeris prediction (called EPO) that gets 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 less than 15 seconds.
Because of the built-in chip antenna, it is easy to install without both RF connector and coaxial cable that are needed in a separated GNSS active antenna. In other words, reduce the cost and size. Also, speed up the time to market by eliminating R&D efforts on RF matching and stability between separated GNSS antenna and module. If the external antenna is required, users can add some external components to achieve the function of automatically switching between the built-in GNSS chip antenna and the external antenna. Furthermore, it can be directly powered by a lithium battery without any external voltage regulars. Therefore, LS2003H-Vx of tiny size and brilliant performance is the best choice to be integrated into your slim devices.
