GRAPHIC DISPLAY Version 1.4 April 2012 |
| Since the fall of 2011, Michel VE2WMG found a way to send the flight informations from an high altitude balloon by FRS or the flight controller. These informations are added at the end of the APRS regular frames and can be easily decoded on a graphic display with a PIC. |
| It is a great help for all recuperation teams when we launch a balloon. |
| When connected to a Kenwood TH-D7 or any radio connected to a TNC the graphic display will decode only APRS frames with the suffix ''-11'' and will display the informations on the screen. It will also show the car GPS informations and will tell you where the balloon is from your car. |
|
|
| The informations received is : |
| Etat FIX : the GPS is active |
| 4539.42N/07234.12W : latitude and longitude the balloon |
| Vitesse : the balloon is travelling at 19kh/hr |
| Direction : the direction of the balloon is 290 degrees |
| Altitude : the altitude of the balloon at 4528 feet |
| Ascension : the plus (+) 197 tell you that the balloon is going up at a rate of 197 feet/minute |
| +21C : temperature inside the box |
| Volt : voltage of the batteries inside the box under the balloon is 9.7v |
| HDOP = Horizontal Dilution of Precision |
| HDOP1.1 : give the
quality of the satellites signal received by the GPS, the smaller the numbers are greater is the quality if the received signal |
| S08 : the GPS is receiving 8 satellites |
| Lest 0% : Quantity of the liquid remaining in the plastic gallon |
|
|
| The second screen gives the informations of the car that is tracking the balloon : |
| Latitude : of the car |
| Longitude : of the car |
| Altitude : the car is at 2011 feet |
| Vitesse : the car speed is 56 km/hr |
| Direction : the car is going at 270 degrees |
| Heure : It is 5:53 |
|
|
| The last screen tells you that the balloon is at 10 km and 270 degrees from the car. |
