Real Time GPS Tracker

We are offering real time gps tracker, gsm sms system, car vehicle tracking, alarm device. The module has built-in gps system to define a geographic location of the object and to transfer the said information to a user's mobile phone. The module transfers messages about event of the security system to the mobile phone of a user via gsm communication channel. Upon alarm response of the security system, the module will generate sms message about alarmed sensors: door, capote, shock, fuel tank etc. Sms message is being sent to a user in -line with a short call. This is to reduce the probability that a user will not observe sms message.
It is possible to send sms and to call to 16 users. The algorithm of message sending is sms1,sms2.smsn till all sms messages will be send. after dial1,dial2.dialn. all messages are being sent until all users will be notified about the event. preferred messages and texts of these messages should be defined when programming the module.
The module understands when the call is rejected and will not repeat calling. When the module is calling to the user’s phone, the user can not reject the call at least 15 seconds. Otherwise the module will understand that the user’s number is busy and will try to repeat the call again. In a case the user’s number is busy in fact, the module will make repetitive calls following the programmed number of calls. efficiency of this function depends on interpretation of call control by the operator; in some cases the operator may wrongly interpret the call and thus the module will make repetitive calls each 60 seconds, following the programmed number of repetitions (by default 3 repetitions). In such case gsm operator may be changed or simply the amount of dial repetitions reduced.
Parameters of the module are set by sending sms or via pc by using standard miniusb cable and configuration software sera.
