Gallery of helical, patch, chip antennas Pictures will tell more than thousand words. GPS antenna helical SMT This inexpensive helical GPS antenna will be mounted direct on PCB. Quadrifilar GPS antenna This Quadrifilar GPS antenna will be mounted on PCB as well. Inside the Quadrifilar GPS antenna is a balun. The GPS antenna is operating […]
Bye, bye GPS – Welcome Glonass
This week I was visiting customers to present the latest GNSS modules. These hybrid GNSS modules are able to receive GPS and Glonass satellites in parallel. We received 17 channels. Just have a look at the video (37 sec). Dark blue bars = GPS satellites with fix Light blue bars = Glonass satellites with fix […]
What will be the power consumption of the GSM GPS Glonass tracker?
The power consumption is from nearly 1 uA to 480 mA in average. The 1 uA we get if we create an asset tracker behind oil on canvas. The asset tracker will wait for an event all the time. The 480 mA we get by GPRS class 10 in GSM power level with TX output […]
