Features of realization
Because of navigation receiver works with two navigation satellites systems, and the acting
standard NMEA does not provide operation on the system GLONASS, some accepted sentences
have extensions. The changes in realization of the some sentences will be indicated in the
description of their format.
In all sentences, except for ZDA, the generation of time and date with allowance of entered
correction of a local time is supposed.
The customer coordinates are transmitted in a selected coordinate system. For want of use of
coordinate systems which are distinct from WGS-84, the sentences DTM informs on a coordinate
system defined by the user (999), and the concrete type of used coordinate system can be obtained
from the PORZX sentences.
After receiver power on the following set-up parameters act for serial ports:
coordinate system
- WGS-84
time -
Greenwich
altitude
- above a sea level (geoid).
