I bought a new toy – GPS receiver (WBT300). It’s very simpleÂ with USB and Bluetooth ports. I do not need it at all, but it’s very curious to play.
Some Chinese software is provided withÂ this device. It shows already decoded information.Â I checked, that coordinates remain quite stable. However, sometimes it’s seems to the device, that it goesÂ somewhere at 0.16km/h speed.Â
I was disappointed in height showing results. The height of my room varies from 60 till 170 m above sea level. I thought, that my house is stably fastened to the ground.
I haven’t demounted this device yet, but theoretically it should has some receiver, transmitter and RS232-USB adapter. The idee fixe appearedÂ to bypass this USB port…
By the way, if you install virtual COM portÂ of Windows, Â the Hyper terminal program will help you to see all data “flowing” out of the device. Here is a sample:
Smarter people can identifyÂ the place and time of the experiment from that rubbish. I also understood several rows. But others remain mysterious.
