While looking through our gateway data to find out some distance records we found interesting gps-tracking results from one of our nodes. During a business trip (on 24th of January 2020) to Vienna (Austria) by car i took one of my TTGO-Beam board with me - its TTN Device-ID is named „jn-ttntracker_1-2“. It is running with standard software from Cyberman54 (github) – without any special modifications (oky we soldered an BME280 sensor to the device). I used a magnetic outdoor antenna on the cars roof-top. While travelling down the A3 highway i watched from time to time the node status – and lots of nearby gateways transfered the location information into the cloud. As we have the ttnmapper integration from JP Meijers running in this application i can follow up now this special travel-data.
First one is pm 3:08:22 our community gateway named „ttn-hennef-gateway04“ listening to all pakets in the air and recieved ID 126298582 from the distance 573,4 km (356,3miles). I am just passing city Wels on the A25 in Austria ….
Next one is pm 3:15:32 – seven minutes later also one of our community gateways named „ttn-siegburg-gateway01“ sent one paket of my tracker to the cloud. Now the distance is 648,5km (403miles). Still driving down the A25 – nearby city is Pöchlarn.
Some more points were tracked in the next minutes until the last one of this series at pm 03:33:33 with a total distance of 649,6 km (404 miles) – some kilometers of city Melk.
This mentioned gateways are Raspberry Pi 3 based with the IMST880a Concetrator board. Running outside with an OMB Taoglas antenna and booth are mounted on roof-tops. We are very proud of this values – thinking about this standard setup without any high-altitude balloon or any special technical laboratory settings. If you are interested in this measurements – just see my device and check the values in TTN. Let me know your opinion about this - is this real ? Or is this something strange in the database ?!
