An attribute inherent in most satellite communications devices is the ability to use them for asset/personnel tracking. I will discuss the various satellite communications platforms and how to implement tracking with each one.
First is a brief summary on how tracking works. The device used for tracking needs to be able to perform two basic functions: 1) acquire a GPS position and 2) send the position report to the internet. Of course, if the position report is being sent, it also needs to be received on the other end. The internet makes this possible and most tracking platforms are web-based, including our own OTrak portal. The portal will receive the report, and plot each position report on a map, and can also perform a myriad of other functions such as geofencing, alerts, speed changes, altitude, heading, etc.
There are many GSM devices that can be used for tracking, but satellite tracking devices are used when GSM is not available or when an asset moves in and out of GSM coverage in order to provide consistent and contiguous reporting. Satellite devices have coverage virtually anywhere since all they need is a line of sight to the sky.
Within satellite platforms there are many different options, but we can break the whole group up into two broad categories: 1) Tracking as an “add-on feature” and 2) Dedicated tracking devices.
Tracking as an “add-on feature”
Several of the handheld satellite phones and most of the larger satellite terminals have built in tracking capabilities.
Handheld Satellite Phones
The Iridium 9575 Extreme is the only handheld satellite phone that can provide stand-alone automated position reporting. It has a built in GPS engine and uses the Iridium SBD (Short Burst Data) service to send position reports. It can also send reports manually via SMS. The Iridium 9555 is capable of sending position reports, but only in conjunction with a docking station that has a built-in GPS engine, such as the Beam 9555SD-G.
The IsatPhone Pro from Inmarsat, on the other hand, can send manual GPS position reports via SMS as a standalone operation and can perform automated reporting when used with a GPS enabled docking station, such as the Beam IsatDock Drive.
Any of the Thrane&Thrane Fleet Broadband terminals can send automated position reports with the latest firmware version. You simply have to go into the tracking menu in the User Interface (UI) and configure your terminal to report to the tracking portal and then register your terminal’s IMEI in the portal.
Similar to Fleet Broadband, any of the Thrane&Thrane BGAN terminals can provide position reporting simply by setting it up in the UI. The Wideye Safari vehicular terminal can also provide reporting directly via the terminal.
Dedicated Tracking Devices
Iridium can provide dedicated tracking via its SBD service. Terminals are available from both ASE and Beam. The terminal requires an antenna, of which a large variety exist, and an antenna cable which connects the antenna to the terminal. The antenna needs to be installed so that it will have visibility to the sky and the terminal requires a DC power source.
Isat Data Pro
Inmarsat’s small packet data platform, the IsatData Pro, is also frequently used as a dedicated tracking device. The IsatData Pro is a one-piece terminal with a built in omnidirectional antenna and is available in three configurations: Marine, Vehicular, and Dual-Mode. The Marine terminal is slightly taller and provides lower look angles to account for pitch and roll, whereas the vehicular version has a lower profile antenna. The dual-mode terminal incorporates least-cost-routing with GSM as the primary service and satellite as the failover. The IsatData Pro is highly configurable so can be set up to receive and transmit a large variety of data input.
For whatever your tracking needs are, there is most certainly a solution to fit them. If you already have a satellite device and are not using it for tracking, then there is more than likely a way to utilize it as a tracking device in addition to any of the other functions it performs.
