Features
The Jupiter series of GPS receivers offers the following physical, operational, and support features:
• OEM product development that is fully supported through application’s engineering.
• compact GPS receiver footprint.
• 12 parallel satellite tracking channels.
• supports NMEA-0183 data protocol.
• direct, differential RTCM SC-104 data capability for improved positioning accuracy (available in both
Navman binary and NMEA host modes.)
• static navigation enhancements to minimise wander due to SA (Selective Availability).
• designed for passive or active antennas for lowest system cost.
• adaptive threshold-based signal detection for improved reception of weak signals.
• maximum navigation accuracy achievable with the Standard Positioning Service (SPS).
• enhanced TTFF upon power-up when in a ‘keep-alive’ power condition before start-up.
• meets strict shock and vibration requirements including low-frequency vibration.
• automatic altitude hold mode from three-dimensional to two-dimensional navigation.
• automatic cold start acquisition process (when no initialisation data is entered by user).
• maximum operational flexibility and configurability via user commands.
• ability to accept externally supplied initialisation data.
• three-satellite navigation start-up from acquisition.
• user selectable satellites.
· user selectable visible satellite mask angle.
