3.5 Differential aiding
3.6 Core processor performance
The standard Jupiter 30 xLP with GSW3 software runs at a CPU clock speed of 49 MHz.
An SDK (Software Development Kit) is available from SiRF to customise the Jupiter 30 xLP
firmware.
3.7 Sensitivity
Sensitivity of the Jupiter 30 xLP is measured assuming a system noise value of 3 dB. The
sensitivity values are as follows:
3.8 Dynamic constraints
The Jupiter 30 xLP receiver is programmed to deliberately lose track if any of the following limits
is exceeded:

3.4.2 Push-To-Fix mode
Push-To-Fix mode always forces the GPS software to revert to a continuous sleep mode
after a navigation position fix. It will stay in sleep mode until woken by activation of the
WAKEUP input (pad 26) to compute a fresh position.
If the ephemeris data become invalid, the RTC has the ability to self activate and refresh the
data, thus keeping the restart TTFF very short.
This mode yields the lowest power consumption of the module, and is ideal where a battery
powered application requires very few position fixes.
3.5.1 Differential GPS (DGPS)
DGPS is not available on the Jupiter 30 xLP.
3.5.2 Satellite Based Augmentation Systems (SBAS)
The Jupiter 30 xLP is capable of receiving SBAS differential corrections including WAAS
and EGNOS. SBAS improves horizontal position accuracy by correcting GPS signal errors
caused by ionospheric disturbances, timing and satellite orbit errors.
