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.

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.

Connectors M.2 also called as NGFF have a chance to become a widely used standard in computers, communication equipment and M2M applications.
The newest member of the data connectors family in our offer are connectors Attend series 123, so called NGFF – New Generation Form Factor connectors, also known as „M.2“. Their main advantage is implementation of PCI Express 3.0, Serial ATA 3.0 and USB 3.0. buses into one connector. The connector is considerable miniaturized and at the length of only 21.8 mm it has up to 75 pins ( 0.5mm pitch/ 50V/0,5A). M.2/ NGFF are designed as a future standard for SSD memory media, WiFi, Bluetooth, GPS/GNSS, NFC and other modules. As it´s not a “specialty” of one producer but it´s a connector designed as an international standard, their usage in your device can be advantageous thanks to a supposed easy availability even in the future. An important fact is, that connectors are produced with various keying (A-M). That provides a possibility to differentiate various modules on one board and prevents improper connection (PCIe x2, PCIe x4,…).
M.2 connectors are designed for a direct insertion of PCB, i.e. one part of a connection (M) is a PCB and another part is the connector (F). Connectors support various PCB widths – 12, 16, 22 and 30 mm. Depending on a type, M.2 connectors also enable a double-sided assembly of components on a PCB.
Another novelties from the Attend production in our stock are interesting types for SIM cards, as well as combinations 2xSIM(115L-AB380), 2XSIM + uSD (115M-AB360) and other, which can be found below this article.

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).

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.
