70mm x 40 mm GSM / GPS tracker
The sketch I made during a three day technical training related to GNSS (GPS, Glonass, Beidou, Galileo, QZSS). The PCB can be even smaller, but this will minimise the efficiency of the antennas. The GPS chip antenna would like to have a ground plane of 22,5 mm left and 22,5 mm right. 22,5 mm x […]
Google Maps Indoor and Google Maps Floor Plan Generator
Recently you can navigate with the new version Google Maps 6.0 in the building. Various airports and shopping centres in the U.S. have already been equipped. To navigate without GNSS signals (no GPS and Glonass) you need some radio beacons along the way. A mixture of natural radio beacons, such as GSM base stations and […]
US LTE operator has interferences with GPS frequency
If you ever travel to US, then is makes maybe sense not to use the operator Lightsquared. Their frequency range of the LTE operator is on the same band than the satellites of GPS. Worst case you cannot use the Google Maps any more. All the other services that use GPS will not operate as […]

GSM and GPS meets short-range radio
OBU (On Board Unit) and short-range radios An inexpensive trailer detection on 2400 MHz radio modules is indeed already published. http://www.gsm-modem.de/M2M/m2m-faq/trailer-detection-active-rfid/ Through the use of ICs, which were developed for consumer products, the bill of materials is very low. Last week, a GSM / ISM Bridge required based on Linux. A GPS module is also […]
