All incoming and outgoing calls, texts and multimedia messages can be seen and interrupted by the Managers, who can also monitor where their Employee are (through GPS), access a history of where they've been and set up alerts if their Employee are going outside of approved geographical zones, are receiving texts from unapproved numbers or calls from banned persons.

It also gives visual representation of various National Marine Electronics Association (NMEA) GPS strings which gives navigational, satellite orbital and clock information.Įmployee monitoring system using android mobile is, essentially, software that allows Managers to monitor their Employee's office cell phone. The system helps in determining signal to noise ratio in decibels of various PRN satellites which is used for determining signal strength of GPS signals for studying Ionospheric scintillation effects on GPS signals. A study of comparison of present and previous geographical location is also available in this system. It is capable of indicating active and inactive PRN number (pseudo random code) of satellites used for GPS tracking in terms of visual plane positioning indicator system. The GPS navigation system presented in this paper provides very useful information about present geographical information which includes latitude, longitude, altitude, current velocity and Greenwich meridian time reference. The main objective of Global positioning system (GPS) is to determine our position on earth in three dimensions: east-west, north- south, and vertical in terms of longitude, latitude and altitude.
