3 1. General Description SKC111 is a multi-purpose module which integrates a high performance GNSS engine and a quad-band GSM/GPRS engine and a highly integrated Bluetooth transceiver. The module s GSM/GPRS engine can work at frequencies of GSM850MHz, EGSM900MHz, DCS1800MHz and PCS1900MHz., with features GPRS multi-slot class 12 and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4. GSM part of SKC111 is integrated with internet service protocols, such as TCP/UDP, FTP and PPP. Extended AT commands have been developed for you to use these Internet service protocols easily. The module s GNSS engine supports various location and navigation applications, including autonomous GPS, GLONASS, GALILEO, BEIDOU, SBAS ranging (WAAS, EGNOS, GAGAN, AND MSAS), QZSS, DGPS(RTCM) and AGPS. In this way, SKC111 auxiliary serial port and GNSS serial port are connected together, so data can be transferred between GSM and GNSS parts. This makes it very convenient for sending AT command to control GNSS, firmware upgrading for GNSS, and EPO data download. It is able to achieve the industry s highest level of sensitivity, accuracy and TTFF with the lowest power consumption. The embedded flash memory provides capacity for storing user-specific configurations and allows for future updates. The module offers a highly integrated Bluetooth radio and baseband processor. It provides superior sensitivity and class1 output power and thus the quality of the connection with a wide range of Bluetooth devices. Figure 1: SKC111 Top View 2.
