WE'VE PUT ALL THE POWER YOU NEED INTO A UNIT THAT'S ONLY THE SIZE OF A STANDARD PAPERBACK BOOK
Aprize Satellite's User Terminal (or "tag") is a small, self-contained device that incorporates a microprocessor, modem, transmitter, receiver, antenna and a battery with a small solar panel for recharging. Excluding the battery, the operational tag is approximately just four-by-seven inches. Its built-in software handles all functions involved in collecting, packaging and transmitting the data it is designed to relay.
The tag receives and stores data for transmission to the orbiting satellites. Its compact design facilitates easy mounting to a variety of payloads, including cargo containers, buoys, pipelines and boats. The tag's case is weatherproof and rugged, allowing it to survive and function in harsh environments.
Using a standard RS-232 interface, the tag can be configured to receive signals from just about any source and convert them into digital data. A transducer that measures everything from barometric pressure to ultraviolet light levels can be accommodated by the tag.
The tag can even be used with a laptop or palmtop computer to transmit short messages from remote sites. These input options make the tag a highly-flexible component because its basic core design is independent of its specific application.
The transmission schedule for each tag can be programmed for a specific application. For example, the tag may be told to transmit data packets every time a satellite is in view or just once a day or once a month - depending on the time-varying nature of its data.
Most of the tags will only transmit when "polled" by a satellite. Controlling the contact times with tags eliminates potential collisions due to simultaneous transmissions and conserves the tag's battery power. The need for batteries is eliminated when the tag can be connected to a power supply at the host site.
All the control you want, delivered from a unit that's just the size of a paperback book. And, in some cases, for less than the cost of the average hardcover bestseller book.
