I wanted to share with you the design of a 2-layer full GNSS board that I have recently developed using Direct RF sampling architecture. The board consists of several blocks, each equipped with SMA input/output connectors, as well as an SMA connection between VCC and GND to check...
I'm seeking assistance with the nt1065_USB3 GNSS receiver manufactured by ntlabs. I've been facing difficulties despite my efforts to make it work properly. Here's a breakdown of my setup and the challenges I'm encountering:
Active antenna: Link to active antenna...
Hello, I'm new to this forum. I hope I'm posting this in the right place.
I'm working on a project that involves the GPS location of safety lights on radio communications towers. I need to show on Google maps the location of each tower, the current state of the lights and battery state.
I am designing a GPS L1(PWR=-160dBW) band Direct RF sampling receiver and the front-end:
(passive antenna + LNA(21dB) + BGA1(30dB) + jumper + BPF(L1(fc=1575.42MHz,BW=15MHZ) + BGA2 (30dB) + BGA3(30dB) + VGA(-13.5 to +18 Gain Control in 0.5 dB Steps) ).
all amplifiers are supplied with a +5 V...
Hello, I discoverd a item taped with Black tape under my car a few days ago. I have tried Google image and I still have No clue what it is. I have a reason to belive it might be a kind of gps but would like to know for sure what it is. Does anyone know what it might be?
Hello, I would like to build a battery powered arduino gps speedometer.
In this arduino based project I would like to include a few features.
-I would like it to turn on some lights when It detects that the speed is going down (if the speedometer is going at 10km per hour and slowing down I...
we are doing a Automotive project.
and we are looking for a GPS chipset which provides us 95% accurate data.
so that we can interface GPS device with with either SPI or UART of ELB-REV4 hardware.
we already have a EC25-E modem in the ELB-REV4 which supports GPS data but this...
UART Communication between GSM and GPS
I want to establish a UART Communication between GSM and GPS.
The Supply Voltage of GPS is 3.3V.
The Supply Voltage of GSM is 3.8V.
The measured RX/TX Voltage Levels of GPS is 2.8V and 0V (for logic High and logic Low).
The measured RX/TX Voltage Levels...
I'm designing a tracker for assets. I want your suggestions to implement into the circuit a method to detect when someone is trying to remove the tracker. I was thinking of surrounding the board with touch pads all around the edges of the board but I guess that would be very sensitive to noise...
I have a PCB made by the electric engineer but we need to make it smaller, maybe stacked? i have seen other GPS simcard designs Stacked, we have no experience designing PCB, maybe you guys can help us make a smaller design keeping all the components.
Thanks in advance for any help
