5 EyesMap Modules
User Manual 92
5.6. GPS
The EyesMap module which allows for the capture and viewing of
coordinates in real time and the capture of data in files for said
data
’s
subsequent conversion to RINEX.
Install the antenna on the upper-right of the tablet if you wish to
capture with the GPS.
This module helps the user to take measurements in absolute coordinates and in real
time and, if the user so requires, to dispose of the necessary data (RINEX files) to
undertake post-processing and increase accuracy.
One can say, in a very simplified way, that a protocol is a way to capture data. The
results obtained depend on the protocol used.
5.6.1. Protocols
EyesMap's GPS can work with many communication protocols; however, in this
manual, we are only going to explain two protocols in detail as these are enough for the
user to take real-time measurements and obtain RINEX data for post-processing.
- NMEA*: Captures data only in real time.
o
It allows you to view data on the screen in real time.
o
If you save a file in this protocol in the real-time screen, it will be an ASCII
file; therefore, it will be easy to read and to find coordinates (this file cannot
be converted to RINEX).

specification.html
- BINR*: Captures data in real time and is necessary to save a file which can be
converted to RINEX (this type of file is necessary to be able to carry out post-
process calculations and get better GPS accuracy).
o
It allows you to view data on the screen in real time.
o
The GPS-GNSS must be set in this protocol for conversion to RINEX.
