Jupiter 3-30
3.7 Sensitivity
Sensitivity of the Jupiter 3-30 is measured assuming a system noise value of 3 dB. The sensitivity values are as follows:
3.8 Dynamic constraints
The Jupiter 3-30 receiver is programmed to deliberately lose track if any of the following limits is exceeded:
3.9 Position and velocity accuracy
The position and velocity accuracy of the Jupiter 30 are shown in Table 3-3, assuming full accuracy C/A code. These values are
the same in normal operation and when Adaptive TricklePower is active.
4.0 Multi-mode aiding
Multi-mode aiding technology makes navigation information available to GPS devices when enough Satellite Vehicles (SVs) are
not visible due to obstruction. In autonomous operation mode, the GPS receiver requires a signal level of 28 dBHz or higher in
four or more SVs to download ephemerides. This requires an uninterrupted full 30 seconds of data reception from each SV. If
the data isn’t received in full, the ephemeris data collection has to start again at the next cycle.
The type of multi-mode aiding currently supported by the Jupiter 3-30 is Ephemeris Push. This feature supports live ephemeris
data to be downloaded from application servers that allows hot start performance at all times including in weak conditions and
moving start ups. The ephemeris would typically be valid for 4 hours until the live ephemeris is downloaded or new ephemeris
data is provided.
To use with this Ephemeris Push, the live ephemeris data is collected at application servers and then transmitted to the GPS
receiver through a network connection. An application note about Ephemeris Push is in preparation and will be available at a
later date.
