General Description

Delin Comm  EM1612-G is a complete GNSS module. The module can simultaneously acquire and track multiple satellite constellations that include GPS, GLONASS, GALILEO, QZSS and SBAS.It features low power and small form factor. Besides, it with superior and performance even in urban canyon and dense foliage environment.
This module supports 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.

Delin Comm EM1612-G GNSS module embedded LNA brings high performance of MTK positioningengine to the industrial applications. It is able to achieve the industry's highest level of sensitivity, accuracy and TTFF with the lowest power consumption in a small-footprint leadless package. With 66 search channels and 22 simultaneous tracking channels, it acquires and tracks satellites in the shortest time even at indoor signal level. The embedded flash memory provides capacity for users to store some useful navigation data and allows for future  updates.EM1612-G module combines many advanced features including EASY, AIC, LOCUS, AlwaysLocate ™ , FLP,Antenna Supervisor and so on. These features are beneficial to accelerate TTFF,improve sensitivity,save consumption and detect antenna status for GNSS system. The module supports various positioning,navigation and industrial applications including autonomous GPS, GLONASS, SBAS (including WAAS, EGNOS,MSAS, and GAGAN),QZSS, and AGNSS.
EM1612-G but also supports external active antenna detection and short protection. The detection and notification of different external active antenna status will be shown in the NMEA message including external active antenna connection, open circuit for antenna and antenna shortage. So host can query the external active antenna  status timely and conveniently.EASY technology as the key feature of EM1612-G is one kind of AGNSS. Capable collecting and processing all internal aiding information like GNSS time , Ephemeris, Last Position,etc.,the GNSS module delivers a very short TTFF in either Hot or Warm start.EM1612-G module is a SMD type module with the compact 16mm×12mm×2.6mm form factor. It can be through the 24-pin pads embedded in your applications. It provides necessary hardware interfaces for connection with the main PCB.Made of lead-free technology, conforms to the RoHS standard, Single patch, two times more rapid application of SMT scheme
