GPS-GSM LOCATION SYSTEM

BUOYTRACKER II builds on the successful BUOYTRACKER GSM system and uses GPS satellite positioning system, together with the GLOBALSTAR low earth orbit satellite data service and allows users to check the position of their buoy from a web page anywhere in the world; no special software is required.  For larger networks, a PC based autotracker program is available to automatically locate any number of buoys or assets with information presented on chart or map.  In addition, BUOYTRACKER II I will watch over your buoy and alert you by email should it wander by more than 500m.  BUOYTRACKERII features a low voltage alarm that will send a message if the host power falls to a dangerous level and sends a heartbeat message at regular intervals confirming correct operation.

 BUOYTRACKER II is totally self contained and can run for up to 3 years on its internal batteries. 

BUOYTRACKER II is small and installation is quick and simple.  The device can be included at build time to be completely covert if required.  Both the GPS antenna and GLOBALSTAR antenna can be fitted inside plastic or GRP buoys.  The enclosure is sealed to IP-68 making it suitable for use in the open on deck in breaking waves.

 BUOYTRACKERII is typically supplied packaged with internal batteries but can be offered with external DC power 

BUOYTRACKERII is available without watch circle mode, but with real-time tracking.  In this mode, the device will wake up at regular intervals and simply report it’s position; ideal for tracking lone ocean crossings, surface drifters, etc.

In operation, a user simply switches on the device, whereupon it will make several measurements of its position to be used as the centre of the watch circle.  Each hour the system wakes up from low power mode, checks its position against the reference and if the position differs by more than 500m, an alarm is sent via GLOBALSTAR communications satellite network.  Alarms are sent as emails and also to a web portal where the position can be seen on google maps.

 Once an alarm message has been sent, the current position is used as the centre for a new watch circle, and checked once again in one hour.  If the beacon has moved again, a new alarm is sent, if not, the beacon returns to sleep mode.

 The system can accommodate inputs from external sensors such as hatch sensors, impact sensors, tilt sensors etc, please ask for additional information.

 A GLOBALSTAR Service contract is required.  Running costs are similar to a cell phone.  Planet Ocean offer a fixed price annual contract covering one heartbeat message per day and 3 alarms a month.

BUOYTRACKER is a unique system for remotely checking the precise location of your buoy or other valuable asset, large or small.

 BUOYTRACKER uses the Navstar GPS satellite positioning system, together with your cellphone text service (GSM SMS) and allows users to check the position of their buoy from a standard mobile phone anywhere in the international GSM network; no special software or PC is required.  For larger networks, a PC based autotracker program is available to automatically locate any number of buoys or assets with information presented on chart or map.

 BUOYTRACKER has user controllable input and output functions that can be monitored and activated via the cellphone.

BUOYTRACKER is small, and installation is quick and simple.  The device can be included at build time to be completely covert.  Both the GPS antenna and GSM antenna can be fitted inside plastic or GRP buoys or boats.  The system is extremely low power and can be supplied from a small re-chargeable backup battery to ensure that the system continues to function for extended periods even if the main buoy power is removed. 

BUOYTRACKER now includes a low battery monitor, and autotrack functions

BUOYTRACKER can be supplied packaged with internal batteries or external power, and as a portable unit for temporary installation if required.

FEATURES:

APPLICATIONS:

In operation, a user simply sends an SMS message to the device which then checks its position, and responds with an SMS message to the users mobile giving latitude and longitude to within 10 m accuracy.  The system can be used to monitor moored buoys, boats, boats underway, or other assets.  Coverage is anywhere within the international GSM network, which generally extends to 15 - 20 kms offshore.  The system can use one of the “Pay As You Go” services so there is no monthly .  rental charge and the card can be topped up from a land phone at any time. 

 The system can be put into watch mode. Sending a special SMS code to the device, instructs it to check its present position.  This position is then confirmed every few hours, and if the system detects a difference of more than 500 metres, an SMS alarm message will be sent to the user, who can then track its movement to arrange a timely recovery. A “waypoint” mode is also available, whereby the unit will send a message when it has arrived at a given location, ideal for monitoring buoy deliveries or transits.

 Because we use the GSM SMS service, even if your phone is switched off or BUOYTRACKER is out of coverage range, you will eventually receive the message as soon as you switch on or BUOYTRACKER comes back into range. The system also incorporates digital inputs and outputs that allow remote control of lights, racons, foghorns etc and monitoring of inputs such as tilt sensors, hull flood detectors, mooring detectors in addition to the position related functions
