SatSCADA for Repeater Site Monitoring


Voice and Data  Repeater system used for critical operations such as public safety, forestry, oil and gas, pipeline, and electric utilities require monitoring to ensure maximum uptime.

Monitoring and control through the existing communications network  may not be feasible if the system does not have these capabilities or it is an separate independent communication media is required to be used for monitoring.

SatSCADA SAT100 RTU featuring low power operation and satellite based communication can provide connectivity where terrestrial communication means such as cellular, radio, or lease line is unavailable.

SatSCADA SAT10 Satellite based RTU is ideal for this purpose.  More about SatSCADA…

The SAT100 RTU features 4 I/O, RS232 & RS485 serial ports, and Inmarsat based global satellite communications.

SAT100 Features

Satellite Communications

Global Inmarsat based geo-satellite ensures real time communication at any time at locations where there is no alternative terrestial means. With SatSCADA there is no outage periods where communications is not available.

RS232 & RS485 Communications

  • Remote RS232 & RS485 Serial Communications to Interface to Repeater Equipment Diagnostics Ports.
  • Connectivity to Repeater Equipment Monitoring Subsystems or to additional I/O.
  • Wireless Sensor Gateway Option – for monitoring external sensors (ie. Fuel Tank Levels) where wired connectivity not feasible or desirable.

Low Power Operation

  • SAT100 RTU Terminals  features low power operation allowing operation at low power repeater sites.
  • SAT100 can also be separately solar powered.

Low power operation is critical for operation at repeater sites. SAT100 systems operate in low power (< 0.3 W – 20 ma at 12 V) and ultra low power (< 0.012 Wat – 1 ma at 12VDC) modes.

SatSCADA Server Support

  • Secure 24/7 Cloud Based Monitoring
  • Secure Multi-user access
  • Site Alarm Notification via SMS/Email
  • Web based Site Monitoring from Laptops,Computers, Tablet & Smartphones.
  • Trending of site variables (Site voltage, RSSI, temperature, site levels).
  • Integration of SatSCADA to third party SCADA Systems via Modbus or CSV Exports.



SatSCADA/SAT100 RTU provides a flexible expandable monitoring solution that can expand from a simple single site system monitoring small number of I/O points – (i.e.  power status & security) to larger scale site monitoring networks.

How Can SAT100 be used to Monitor Site Voltage?

The SAT100 has internal voltage monitoring. If you power the SAT100 from the same voltage source as the site equipment, the site voltage can be monitored (10 – 30 VDC operation range).

Can the SAT100 be used to Monitor Intrusion?

The SAT100 has inputs that can be configured in digital input mode. Connect a proximity switch input (NO/NC) to this input and set the input alarm state and  alarm delay time appropriately.

Can the SAT100 be used to Reset Remote Equipment?

The SAT100 as digital outputs that can be configured in PULSE output mode. These outputs can be connected a relay with NO/NC contacts. If you power your equipment that you would like to reset via power connected through the NC contact of this relay, a PULSE command from the GUI (output set up for about 1-2 seconds) will reset your equipment. The SAT100 operated this mode does not draw any additional power since the relay is normally de-energized.
