LS2003x-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 sub-meter position accuracy. It can provide you with fast Time-To-First-Fix, superior sensitivity and low power consumption. Its far-reaching capability meets the sensitivity requirements of car navigation as well as other location-based applications.
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. The RF front ends of LS20030-V3, LS20031-V3 and LS20032-V3 are specifically designed to comply with sensitivity specification contained in AIS 140 standard. They are the best solutions to those customers that design tracking applications in compliance with AIS 140.
