SC16C2552BIA44

With the rapid development of GPS (Global Positioning System) techniques, GPS gets wider application in many fields. GPS has features such as high precision, global coverage, convenience, high quality, and low cost. Recently, the use of GPS extends speedily from military to civilian applications such as automobile navigation systems which combine the GPS system, e-map, and wireless network. GPS is getting popular, and the market for GPS techniques is extending continuously.

UARTs provide serial asynchronous receive data synchronization, parallel-to-serial and serial-to-parallel data conversion for both the transmitter and receiver sections. These functions are necessary for converting the serial data stream into parallel data that is required with digital systems. Synchronization for the serial data stream is accomplished by adding start and stop bits to the transmit data to form a data character. Data integrity is ensured by attaching a parity bit to the data character. The parity bit is checked by the receiver for any transmission bit errors.

The circuit describes how to combine GPS into a navigation system by using a Philips 2-channel UART, the SC16C2552B. The SC16C2552B is a two channel Universal Asynchronous Receiver and Transmitter (UART) used for serial data communications. Its principal function is to convert parallel data into serial data, and vice versa. The UART can handle serial data rates up to 5 Mbit/s.

We made a step by step article about how to track vehicles using Arduino + GPRS / GPS. Then we integrated the information using the Google Maps API. All the code is available with open source license.

Check out Cooking Hacks Arduino-based GPS tracker project for vehicles that could be extremely helpful to pinpoint the exact location of the vehicle in case it is stolen. The project uses a GPS+GPRS shield with an antenna to locate the coordinates of the vehicle. You need to call the device from your preset phone number, which will be verified by the SIM908 module on the tracker, and it will then send you an SMS with the GPS coordinates of its location.

Built on the basis of Arduino UNO, GPS, SD card, TFT, GPS map navigation system is to obtain the real-time position information via GPS, to send it to UNO for calculation, according to the calculating results, and teamed up with the

map file stored in SD card, thus presenting the position on TFT. The GPS system, owing the function to store the current position information, can be applied to running positioning and to record the running tracing.

Track and Trace anything with the Arduino AnyTracer of only 25 x 25 mm! It is the smallest, complete GPS GSM tracker in the entire world.

A movie is not necessary here! The photos speak for itself. Together with the best Italian and Russian GPS specialists we managed to make the smallest complete GPS GSM tracker in the world. This tracker is only 25 x 25 mm! With the onboard STM32 microcontroller you can program it yourself with Arduino or online (!) with Mbed.org or in C using Keil or the opensource CooCox IDE. Almost anybody can do the programming with their own beloved platform.

GPS-shield

By Boris Landoni @ open-electronics.org:

By coupling a standard NMEA GPS receiver and an Arduino board we created a super simple and effective Arduino GPS logger. This device allows you to trace the route taken by a person or vehicle (or any other moving object) by simply doing a periodic caching of location points coming from the GPS unit. As the logger saves the list of records (containing data on recorded positions) on a microSD memory card, you can then move the data onto your computer and keep track of your trip. You can use tracked data to help project such as OpenStreetMap to grow and include new areas (www.openstreetmap.org).

DistanceMeter

Raj @ embedded-lab.com writes:

A group of students at Indiana university has built an Arduino-based distance measuring tool as their class project. It is a handheld device that measures the distance between any two points using the latitude and longitude coordinates (received from GPS satellite) of the points. It provides distance output in Yards and is useful for sports applications, such as in golfing to compute the distance between where a ball is hit and where it ends up.

New antenna 2J620P will provide you a high quality GSM and GPS signal at once, moreover with a very simple assembly.

Tracking of vehicles or goods is still more used what naturally results into a requirement for a suitable antenna. One of them can be the 2J620P. It offers a very simple and elegant solution, as in fact it is “2 in 1” – two antennas in one enclosure, each with a separate RG174 cable and SMA connector. Assembly is absolutely simple – by means of included double-sided foam pad. Also supplied is even a small towel filled by isopropanol for cleaning of a place of assembly as well as antenna itself.

2J620P has a 2.14 dBi gain for GSM and 26-28 dB for GPS. The GPS portion is equipped by an active amplifier, that´s why requires 2.7-5.5V/15-25 mA power supply. In many applications can be also advantageous a flat shape without any nibs.

Detailed description of the antenna can be found in the 2J620P datasheet.

59732-imec1

A new multi-band satellite antenna developed by Imec in collaboration with Septentrio was announced at the Mobile World Conference held recently in Barcelona, Spain. The antenna is a multi-band design capable of simultaneously receiving GPS, GLONASS, BeiDou and GALILEO satellite signals. The resulting receiver is capable of resolving its location to within 1 cm.

The antenna is paired with Septentrio’s credit card-sized AsteRx-m receiver, a dual frequency GNSS (Global Navigation Satellite Systems) receiver that provides centimetre accuracy while drawing less than 500 mW
