Actually, our company happens to be the lone and local supplier of GSM/GPS modules that is being used for application like tracking device, fleet management, telemetry, and telematics. Tracking system is so familiar in Europe, US and some parts of Asia and there are a lot of manufacturers for this product. In Phils, the pioneering companies are Webcast Tech the maker of Track Me, Find Me, and Secure Me; all are using our GSM/GPS module. Another co like ANTS, the maker of Gotcha also uses our GSM/GPS modules. Other co like Starcom is also on this line of business. I can name the first 2 as the major tracking companies that boast of their mapping system and sophisticated rover. BUT most of their prices ranges from 18k to 30k pesos each (rover price, except for the subscription) depending on the package you get. Basically, these companies are selling their mapping system and the only way to do that is to sell a hardware device like a GSM/GPS tracking device.
Good thing, one of my customer is able to do and build a low cost GSM tracking device for 15k (addional 1k for the installation) and does the same feature these 2 companies are now implementing. Although the device has no GPS on it, but the PCB has the footprint of the GPS in case the customer decided to upgrade it. Features like engine immobilizer/mobilizer, door lock, and sending of alarm all via SMS. For tracking, you can just enroll your SIM with Smart or Globe's person finder. For more info, kindly PM me for those interested customer. I think they can also accept customization of the device depending on the preference of the customer. Also, they can even give discounts for group package, and what I can guarantee you is the quality of it.
