2.0 Technical description The Jupiter 110 module provides a 12-channel GPS receiver and patch antenna in an open board design that is compact, versatile and easy to adopt. The Jupiter 110 is available in four configurations: • Jupiter 110 (standard) – GSW2 navigation software •...
2.4 Physical characteristics The Jupiter 110 is an open frame structure on a single PCB, with patch antenna mounted on the upper surface and the GPS receiver components housed on the lower surface.
The battery backup input line powers the RTC section of the baseband receiver. Supplying power to this pin is required for normal operation and ensures that the RTC continues to operate even when the main power is interrupted. Refer to Table 4-1 for the Jupiter 110 battery backup supply voltages.
3.7 Core processor performance The standard Jupiter 110 with GSW2 software runs at a CPU clock speed of 12.28 MHz. Using XTrac software (Jupiter 110S and 110RS), the clock speed increases to 24.5 MHz. An SDK (Software Development Kit) is available from SiRF to customise the Jupiter 110 firmware.
The following sections describe the software protocol, including the default NMEA-0183 (v2.2) protocol. 6.1 NMEA output The Jupiter 110 has a default data transmission speed of 9 600 Baud. The update rate is once per second. The configuration parameters set via the NMEA command sentences are stored in battery backed memory and will be used at power up.
