1. Introduction
- Introduction
Globalsat has been a pioneer in presenting innovating products especially around SiRF III enabled GPS devices. The latest announcement about a SiRF III device with tracking abilities raised our curioucity and therefore we decided to review the new TR-101 device.
- Globalsat TR-101
The GlobalSat TR-101 is a personal remote positioning device with built-in GPS and GSM modules. It is compact and portable. There are three speed-dial keys and one emergency key on the Globalsat TR-101. You can use these features for protecting and searching for children and old people. You can use it as a security device to track anything that needs remote monitoring.

• GPS personal locator.
• GSM/SMS communication.
• Omni-directional high sensitivity GPS antenna which can receive GPS signal from all direction.
• New technology and latest SiRF Star III chipset! Excellent for fixing the position even at a weak signal status.
• Remote command control via mobile phones and/or through online software.
• Receive phone calls to have two way communications.
• It can filter incoming calls for up to 10 phone numbers. Only these 10 numbers can call in to the TR-101's and check its position.
• 3 quick dialing buttons for preset phone numbers.
• Works worldwide since supports 4-frequency GSM 850/900/1800/1900 MHz.
• SOS button send out exact location for immediate rescue/action.
• Independent SOS (emergency) button which will send GPS location information via SMS for up to 3 preset numbers (it can be 3 sets of different numbers than the 3 sets of quick dialing numbers).
