Hello, For navigation does we require any telecom tower? just gps module is connected to satellite directly?
It looks like a ceramic gps antenna to me.
Good day to all, Firstly, I want to apologize if I'm writting in the wrong forum. :oops: Now, on to the business. I have bought a gps Bee kit (a u-blox Neo 6M gps module in a XBee compatible board) and I'm having a huge headache thanks to it (photos of the module are in the attachments). The problem is that it appears (...)
Hello. We at are lokking for someone that can help us make a very small run of a custom circuit. The main components will be gsm chip, gps, chip, acclerometer, and a blt 4.0 module. As you might understand we are not pro at this heavey electronic stuff, but we got a full brief and mockups, dimension and even a early test circuit
I heard first time gps module with SPI, Anyways Try going step by step first connect only gps module and then GSM. And display data received on LCD or any terminal for easy debugging.
Hi, The interface between the gps module(specific manufacturer) & LPC2148 is the serial communication like UART. The module continuously sends that serial data containing the location parameters like longitude & latitude etc... In the serial data string first six bytes matches with the string like ($GPGGA) then it is considered as valid (...)
Guys, I'm trying to interface gps module mt3333 with 8051 but unsuccessful til now. My gps module is not showing me proper values in hyper terminal, i.e. it is not showing me latitude or longitude. Also in $GPRMC statement it is showing a letter 'V' which stands for data not valid. So can anyone help me with this so that it (...)

I am very new to GSM/GPRS modules. I am trying to make a project where a SMS/CALL needs to be sent to a mobile number. My questions are very basic, would be really grateful if someone could deal that. 1. Can the SIMCOM GSM/GPRS modules be programmed as we program MCUs like AVR or PIC? or they can only controlled by AT commands or LUA? 2. Ca
Hi, I'm planning to buy GSM module from AliExpress, as generally available modules are SIM900 or SIM808 as on. I want to know does these modules are supported by most of service providers? like TELUS, Bell etc. Thanks. SIM900 is for GSM and GPRS. SIM808 for GSM+GPRS and gps. both modules are for (...)
What is the question exactly? Every modern gps module I know of has a PPS output.
Hi, I interface gps module with At89c2051 micro controller and i was able to isolate GPRMC data. However, i just wanted to process further latitude, logitude etc. After modifying the code, again i received other data formats (GPVTG) without processing the data. I want to print the data in second line. So i made the LCD command for that. (Howev
You cannot directly use the SIM548 in SIM908 breakout board. There are some modifications on the module, unlike SIM908, SIM548 has separate Power pin for gps , and one extra Serial UART for gps, gps RTC core to help hot Start, etc but if you are only looking for the GSM part, All the functions are exactly same as SIM908
Hey guys, I have a gps module from Skylabs. I have interfaced it with Atmega16 and got the latitude & longitude values. I was wondering, is there any android app to which i can send the latitude and longitude values via bluetooth (From Microcontroller to App)?

Hi, im benarjee working on the I-Lotus FC on core gps module.i want to know about the response command coming from the gps @@Pg Command has total 19 bytes .wt is the descriptio of the total 19 bytes in @@Pg command. i got the struck here. Thanx in advance.
what you are looking for is a WARM START UP so try changing to AT+CgpsRST=1 or try maybe =2, the manual states that it's better to make a cold reset the first time (=0 like yours) but after that, subsequent resets could be =1 (some pages states =1 is auto, another page states that =1 is hot and =2 is warm) sadly this module doesn't say exactly ho
Hello everyone, Happy to see you after long time. Now I am working with gps modules L80 and SKG-13C... I only designed the PCB board and schematic. Schematic is same they were used in datasheet. My problem is when I gave power (3.3V) to the board nothing happening. 1PPS pin remains same( about 0V)... Vbackup is connected to VCC I tho
Hello, Did someone experience with simulation of RF PCBs (e.g. gps). The signal propagation chain looks like this: Antenna gps --> --> LNA --> SW filter --> gps module (e.g. from u-blox) All modules in such chain (except matching networks and antenna) have either Spice models either S-parameters.

I am using Atmega 32 Application needs 2 Rx lines. In fact using GSM modem and gps module. It needs communication with both, but I need one at a time only. GSM needs both Rx and Tx, : so giving the serial port to this. One more Rx is needed for gps module. I wish to use 74LS257 multiplexer to select one of the two (...)
1) Sadly I think you'll never find a RFID system with a 1-2 meter range, the lack of powersource in the tag make them work in small distances only... (I think I have seen one that works at 30cm tops) better if you put your sensor only near the person (via a pole or something) and the rest of your circuit on the wall communicating with the sensor [w
