GPS Monitor

The task GPS\GLONASS Monitor is intended for interaction with GPS\GLONASS receiver connected to the computer through serial port of computer (COM1: COM2:) or USB computer port.

Main service functions:

1. Connection, customization of connection with the receiver (device).

2. Display of the conditional location of the satellites on the celestial sphere, accuracy of measurements.

3. Displaying and analysis of messages from the receiver.

4. Transfer of commands to the receiver.

5. Various manipulations with coordinates of a point (displaying on a map, the saving as a separate point object, saving of a line at movement of receiver as linear object).

6. Performance of queries:

- information on device (unique number of the device, version of software, a series, etc.);

- way-points;

- routes.

7. Testing the task GPS\GLONASS Monitor.

A bookmark of dialog corresponds to the each option:

- Tuning of port;

- Satellites;

- Coordinates;

- Parameters;

- Map;

- Input;

- Output;

- Service;

- Test.

At correct opening of a port and correct connection with the receiver from the device the information immediately starts to go, this information is displayed on the Input bookmark.

After the GPS\GLONASS receiver has been oriented and has caught not less than 3 satellites, it is capable to define the coordinates, which are displayed on the Coordinates bookmark. For displaying the received point on your map include a tick Show point on map. Thus, the map moves so that the point (indicated by blinking cross-hairs or by the conventional sign specified on the Parameters bookmark) appears in the middle of a document window.

At tracking moving object for orientation of a map on a course of movement use a tick:To turn a  map on a course of movement. Parameters of map turn can be changed on the Parameters bookmark.

If there is no opportunity to experiment with GPS\GLONASS receiver, to get acquainted with work of the task GPS\GLONASS monitor it is possible, having included a test mode (Test mode check-box). The choice of a testing mode is carried out on the Test bookmark.

Ready algorithms:

Order of actions at connection of GPS\GLONASS receiver to COM-port;

Order of actions at connection of GPS\GLONASS receiver to USB-port;

Order of actions for start of a test mode Movement on the chosen object;

Order of actions for start of a test mode Loading of the protocol of format NMEA 0183 in real time;

Order of actions for saving a point on a map in the form of point object;

Order of actions for saving a point on a map in the form of linear object;

Connection of GPS-receiver GlobaSat BU-353 / BU-353s4 / BR-355s4/MR-350s4.

Some restrictions for the GPS Monitor task:

- messages from GPS\GLONASS receiver should arrive in NMEA 0183 format at connection via COM port and in Garmin format at connection via USB;

- WGS-84 should be set as the system of coordinates in GPS receiver;

- work is carried out on a map supporting recalculation to system of coordinates WGS-84.
