Collect and send the coordinates to the server. The FTP. The NMEA
78 USD It has to work as a service, it has to start automatically.
- with open source (Specially, if the dll is used it should also be open),
- ability to record from 3 com ports at the same time, i.e. from 3 gps
Data transmission should be protected, even if encryption is simple.Removing from the NMEA signal ports are GPS coordinates, and further sending them in automatic mode with the specified ftp interval for example, or somehow otherwise, on the server side where the sending will be (it needs to organize a check if the data has arrived.Likewise, the client is very bad internet, sometimes there is no internet for a few days, but the information should be collected (copied) and then sent), it should all be collected in a single base, then it should be possible to display the tracks data on google earth\ maps or analogue.GPS data is stored every 5 minutes and sent to the server (ftp or otherwise).The program must have the function of changing the time of data collection.5 , 10 , 15 , 20 minutes , it is best to simply indicate by entering time in minutes.If the computer is restarted, the program must start automatically and continue to collect data.You can think of checking it works or not, for example, if you haven’t come to the remote service of the coordinate 4 times for example, then send a message to the mail that the system does not send the data.I can decide any other way, I'm waiting for your suggestions.
Client's review of cooperation with Aleks Horbenko
Collect and send the coordinates to the server. The FTP. The NMEAVery good quality, I'm still testing, but everything works and as needed.

It will require access to the machine at a certain time to which the COM port is connected. if there is documentation on the protocol of exchange with the device it will not be overwhelming (especially if, in addition to the necessary data, the GPS gives any official or other information that you need to cut off)
The price/frame does not include the following item.
“There should be the possibility to display the tracks on Google Earth maps or an analogue. “The
It also does not include any work on the side of the server to which the data to be sent (e.g. data encryption if it is required to be encrypted).
That is, the price and time limits only for the collection of data from the COM port, possible their temporary sorting, temporary logging and storage on the local machine, FTP transmission control, and the data transmission itself. All of this is in the form of service. The originals will naturally be attached. The implementation was not on C/S++ but on the assembler, but it will not work worse than that.
… The remaining points require clarification and are likely to go beyond the deadlines and budget.

Доброго времени суток. А принципиальна ли передача данных на ftp, или возможен вариант с веб сервером ?

Да можно реализовать хранение данных в бд. С возможной последующей выгрузкой...
