Satellite Mask Settings
Once the NAVIOR-24S GPS/GLONASS receiver has acquired and locked onto a set of satellites,
which pass the mask criteria listed in this section, and has obtained a valid ephemeris for each
satellite, it will output regular position, velocity and time reports according to the selected protocol.
The default satellite masks observed by the NAVIOR-24S GPS/GLONASS receiver are listed in
Table IV-1. These masks serve as the screening criteria for satellites used in fix computations and
ensure that position solutions meet a minimum level of accuracy. The NAVIOR-24S
GPS/GLONASS receiver will only output position, course, speed and time when a satellite set can
be acquired which meets all of the mask criteria. The satellite masks can be adjusted in
GPS/GLONASS receivers accepting the BINR protocol packet 0Dh. (See Appendix A for details on
key setup parameters.)
