Yes we are trying to make our products with multiplatform capability.
A bigger problem that has been faced by Organizations continuously with Software Products is handling data on different Operating Systems and with the different look for different OS. They really struggle while transferring data from one OS to other OS. Today there are only few software products are available in the Market which shows the capability of Multi Platforms capability.

Yes user will require different builds for different platforms. There won't be any extra cost for it. It comes with the product features whatever he/she bought from us. It is in the plan.

Global Positioning System. A Network of Satellites that continuously transmit coded information, which makes it possible to precisely identify locations on earth by measuring earth from satellites. As stated in the definition above, GPS stands for Global Positioning System, and refers to a group of U.S. Department of Defense satellites constantly circling the earth. The satellites transmit very low power radio signals allowing anyone with a GPS receiver to determine their location on the earth.

GPS has a variety of applications on land, at sea and in the air. Basically, GPS allows you to record or create locations from places on the earth and help you navigate to and from those spots. The most common airborne applications include navigation by general aviation and commercial aircraft. At sea, GPS is typically used for navigation by recreational boaters and fishing enthusiasts.

Land based applications are more diverse. The scientific community uses GPS for its precision timing capability and a myriad of other applications. Surveyors use for an increasing portion of their work. GPS offers an incredible cost savings by drastically reducing setup time at the survey sites. It also provides amazing accuracy. GPS is becoming increasingly popular among hikers, hunters, snowmobiles, mountain bikers, and cross countries skiers, just to name a few.
GPS is rapidly becoming common place in automobiles as well. Some basic systems are already in place, providing emergency roadside assistance at the push of a button (by transmitting your current position to a dispatch center). More sophisticated system can show the vehicle’s position on an electronic map display, allowing drivers to keep track of where they are and look up street addresses, restaurants, hotels and other destinations. Some systems can even create a route and give turn by turn direction to designated location.

The Tro GPS Simulator provides a complete suite for all your GPS simulating needs and more. The Tro GPS Simulator uses the international standardized protocol NMEA-0183 for GPS data exchange. This standard is specified by the National Marine Electronics Association and contains mechanisms to exchange data in an interoperable way. The Tro GPS Simulator provides the simulation for GPS Receiver on following interfaces:

(a) Serial Port (RS232)
(b) Network (TCP/IP)

These interfaces can be used at the same time. A Serial Port only provides exclusive access while the Network interface provides multithreaded access. That means Tro GPS Simulator can be used as multiplexer. It provides five input methods for GPS data:

The National Marine Electronics Association (NMEA) is the unifying force behind the entire marine electronics industry, bringing together all aspects of the industry for the betterment of all in our business. It is a non-profit association composed of manufacturers, distributors, dealers, educational institutions, and others interested in peripheral marine electronics occupations. Click here to read more

NMEA-0183 standard is the communication protocol (set of rules) by which GPS (Global Positioning System) units communicate with other devices. It uses a simple ASCII (American Standard Code for Information Interchange), serial communications protocol that defines how data is transmitted in a "sentence" from one "talker" to one "listener" at a time. NMEA-0183 data is sent at 4800-baud rate. Its implementations vary, but can often interoperate with RS-232, RS-423, and RS-422. Click here to read more

In computer networking, a port is an application-specific or process-specific software construct serving as a communications endpoint. It is used by the transport protocols of the Internet Protocol Suite, such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP)

A specific port is identified by its number, commonly known as the port number, the IP address with which it is associated, and the type of transport protocol used for communication

A serial port is a serial communication physical interface through which information transfers in or out one bit at a time (contrast parallel port). The term "serial port" usually identifies hardware more or less compliant to the RS-232 standard, intended to interface with a modem or with a similar communication device.

Serial ports are still used in applications such as industrial automation systems, scientific instruments, shop till systems and some industrial and consumer products. Serial ports are still used in these areas as they are simple, cheap and their console functions are highly standardized and widespread.

TCP/IP is the communication protocol for the internet. TCP/IP defines the rule computers must follow to communicate with each other over the internet.

TCP provides a communication service at an intermediate level between an application program and the Internet Protocol (IP). That is, when an application program desires to send a large chunk of data across the Internet using IP, instead of breaking the data into IP-sized pieces and issuing a series of IP requests, the software can issue a single request to TCP and let TCP handle the IP details.
