Example 8 - Reading and writing GPS data

Example 8a - Read out GPS:​

Task:​

Read out GPS signal and process it further.

Solution:​

gps = $'GPS.Location';
gpsInfo = sFormat("Lat: %.8f °N, Lon: %.8f °E, Alt: %.1f m", gps[0], gps[1], gps[2]);

Functions used:​

Explanation:​

  • gps: The result variable gps is a vector with 3 elements that can be indexed using the [...] syntax. Here, gps[0] is the latitude, gps[1] the longitude and gps[2] the altitude.

For the general use of vectors, please refer to these sections of the online documentation:

Example 8b - Write GPS:​

Task:​

Build a Gps variable in the smartCORE from individual channels for latitude and longitude (or altitude), which can then be used in the usual places (OSF, optiCloud, geoFence, etc.).

Solution​

latitude = 49.89367167;
longitude = 8.82370667;
gpsDieburg = [latitude, longitude, 140.0]; // Order [<lat>, <lon>, <alt>]
gpsBlurred = [0.01 * round(gps[0] * 100), 0.01 * round(gps[1] * 100), 0.0];

Functions used:​

Explanation:​

  • To build a Gps variable in smartCORE, a 3-component vector must be constructed using the [...] syntax as above:
  • The local variables latitude and longitude can of course be derived from calculations, a table or the original GPS position.

If no data type "gpsLocation" is available in optiCONTROL, make sure that you are using the latest version of optiCONTROL.
