Solara Field Tracker Operation
- Messages are generated in each Solara Tracker 2100 or 2000 unit according to the pre-programmed sequence and/or by external commands
- Depending on the model, the Solara Field Tracker then transmits the message to an Orbcomm or Iridium low-earth orbit (LEO) satellite when it is in view
- If it is an Orbcomm tracker, the satellite relays the message to an earth station if it is within view, or stores the message on-board and downloads it as soon as a station is visible. If it is an Iridium tracker, all messages generally are transmitted within 20 seconds.
- The acknowledgement of message receipt is sent back to the Solara Field Tracker unit. If the Solara Field Tracker does not receive acknowledgement within a specific time period from the satellite, the message is re-transmitted to the next satellite in view.
- The message is forwarded to the Solara central server by the satellite system
- The Solara server saves a copy of the position reports, and forwards the positions to the connected map users who have permission to see the reports. Users can also request past histories from the server - there is no limit on the back-date of archived data. Users can also call up any message sent.
- If the user chooses to do so, a "Notify Reply" message can be sent to the Solara Field Tracker unit in the field from a computer running the map client or by logging into the Subscriber Area of this Solara Web Site and choosing the appropriate menus.
Both the Solara Field Tracker 2100 and Solara Field Tracker 2000 use the Iridium satellite system to send and receive messages. The Solara Field Tracker 1000 uses the Orbcomm satellite system to send and receive messages.
Field User Operation
To operate a Solara Field Tracker, the field user connects power to the unit (battery and/or external 12V power), then opens the case (if a case model) and turns on the power switch. The power LED will illuminate, indicating the tracker is on.
The Tracker will transmit the user's position on a timed interval. The interval can be modified over-the-air without the need to connect directly to the unit.
The "default" configuration for Iridium based Solara Field Tracker 2100 or 2000 will record a position every 15 minutes. Orbcomm based Solara Field Trackers record positions every 12 minutes, and then transmits all 5 stored positions every hour. Other users at home or office with a computer and Internet connection will see the position trail of the Solara Field Tracker on a web-based map as each transmission is received from the satellites. Locations can also be relayed by email, fax or telephone as part of the set-up.
If a field user with a Solara Tracker 2100 or 2000 turns on the "Notify" switch, a special "Notify" message is sent over the satellite system to the users monitoring the Tracker positions on the computer.
On receipt of the notification, a window pops up on the screen of a computer monitoring positions with details on the location and Solara Field Tracker ID sending the notification. Once the user monitoring the Solara Field Tracker positions is aware of the notification, they acknowledge the receipt of this message by hitting a key that sends a message back to the Solara Field Tracker through the satellite system.
Once this acknowledgement message is received by the Solara Field Tracker, a yellow "Notify Reply" LED is illuminated on the Tracker switch plate. The field user now knows the notification has been heard and is being acted upon.
It is up to the user to pre-determine the response to the notification. If the user has indicated to the Solara Web setup utility that they wish to have other means of contacting them when a notification message is received, the Solara server system will call telephone numbers previously defined by the Solara Field Tracker owner to notify the person answering the telephone that a notification has been received.
If there is no answer on the first number tried, additional numbers are tried if they have been set up by the Web utility user. If there is no answer at any of these numbers, a Solara operator will attempt to contact other responsible authorities according to an escalation list prepared in advance with the Tracker owner.
