Receiver Performance
The NAVIOR-24S GPS/GLONASS receiver is a complete 24-channel parallel tracking
GPS/GLONASS/SBAS receiver designed to operate with the L1 frequency, Standard Position
Service, C/A code for GPS and CT code for GLONASS. Using three highly integrated NAVIS
custom integrated circuits, the receiver is designed in format for embedded applications.
The receiver features NAVIS latest signal processing code, a high gain RF section for compatibility
with 18 dB active gain GPS/GLONASS antennas, and a CMOS level pulse-per-second (PPS)
output for timing applications or for use as a general purpose synchronization signal.
The NAVIOR-24S GPS/GLONASS receiver acquires a position fix with minimal delay after power
cycling. The battery back-up RAM is used to keep the Real Time clock (RTC) alive, and to store
the following:
•
Almanac
•
Ephemeris
• Last position
No user settings can be stored in the receiver’s non-volatile (Flash) memory. These settings are
retained without application of main power or battery back-up power.
The NAVIOR-24S GPS/GLONASS receiver has two configurable serial I/O communication ports.
Warning – When customizing port assignments or characteristics, confirm that your changes
do not affect your ability to communicate with the receiver (see Chapter 3, Software
Interface).
