AMPGS SAT Pro 1000 processes GPS satellite signals to obtain its position in terms of longitude and latitude and transmits this information over AMGPS’s Satellite Network. In addition to position information, SAT Pro 1000 transmits other message types that include battery status, input alarm status and diagnostic information. The SAT Pro 1000 is configured using a computer and USB configuration cable to communicate these messages at certain times and/or under certain conditions.
Inputs
The SAT Pro 1000 has an I/O port that provides ground, two dry contact inputs, power and soft-power down inputs. The SAT Pro 1000 allows sending Input Status Changed Messages for both Input 1 and Input 2. The Inputs must be asserted for at least 5 seconds in order to be acknowledged.
Usage Example: A construction company needs to document, per their contract, when they begin their work day and when they end their work day. Based on this requirement, the SAT Pro 1000 would be connected to the ignition switch and configured to send a transmission with location when the input changes state.
AMGPS SAT Pro 1000 also allows the user to define the Message Interval while the Inputs are in an Undesired State, either Opened or Closed.
Usage Example: A company has remote containers at job sites and would like to know if a door is ajar. If a door is left ajar the company would like a notification every 2 hours. Based on this requirement, the SAT Pro 1000 would be connected to an open door sensor with the Undesired Input State Message enabled and set as Opened with a Message Interval of 2 hours.
Note: The SAT Pro 1000 uses a 5 minute “hysteresis” window to prevent sending false alarms. This means that only one status change message can be sent during any 5 minute time window. Any subsequent status changes will be detected but not reported. Multiple status changes during any 5 minute window will result in the transmission of incorrect trigger bits.
AMGPS SAT Pro 1000 has the ability to send an Accumulate/Count Message at a regular configurable interval and/or based on configurable multiples of accumulated hours and/or number of counted events or hours of vibration.
Usage Example 1: A construction company needs weekly engine run times for their heavy equipment to manage their maintenance scheduling. Based on this requirement, the company would schedule a weekly Accumulate/Count Message.
Usage Example 2: A construction company wants to insure that no equipment is ever operated beyond 400 hours without maintenance. Based on this requirement, the company would schedule an Accumulate/Count Message for every 400 hours of use.
AMGPS SAT Pro 1000 has the ability to send both Status Change and Undesired State messages based on vibration.
Configuration
The SAT Pro 1000 comes ready to use with a factory configuration loaded in the device. The factory configuration, Standard Messaging without Motion and Interval Messaging of 12 hours, may be changed using the SAT Pro 1000 Configuration Software, the USB Configuration Cable and a PC.
Power supply
AMGPS SAT Pro 1000 is powered by, and comes with, four installed 1.5v Lithium AAA batteries.
Satellite Communication
The SAT Pro 1000 communicates with both the GPS satellite network and the AMGPS Satellite Network. All GPS locations are pulled from the GPS network and all transmissions are sent via the AMGPS Satellite Network. The SAT Pro 1000 has the unique ability to check its GPS coordinates at a programmable rate while it is inside of the Change of Location Area without actually sending a message over the AMGPS Satellite Network.
For a Location Message, the SAT Pro 1000 will wake up at a scheduled interval or time of day and begin to acquire a GPS fix. Once it receives its GPS fix, the SAT Pro 1000 will transmit its location to the AMGPS Satellite Network.
