Integrated Sky Monitor

Integrated Sky Monitor

description

The ISM relies on a full powered Intel iCore system. The C++ software is partially open source and it is possible to access data for additional processing. The platform runs Linux Debian. Over 80% CPU is free for onboard data processing.

The small form factor and low energy requirement make the ISM easy to deploy in the field, even with solar powered batteries. Data may be backhauled using a low bandwidth mobile network over IP.

The ISM is composed of three appliances with a total power requirement <40W:

  • ISM main unit 15x17x17cm, 2.8kg IP67
  • Night Seeing Monitor, 38x16x16cm, 2.5kg IP67
  • External sensors, pylon mounted, 36x24x37, 2kg IP67

About us

MIRATLAS SAS, designs and manufactures the Integrated Sky Monitor (ISM), which provides overlapping, continuous, live real-time, high resolution monitoring of the sky and atmospheric conditions.

The ISM is built for autonomous, remote 24/7/365 outdoor operation including a wide suite of  passive optical instruments available for the first time in such compact and easy to install package.

Deployed in network, ISMs allow simultaneous survey of potential sites for FSO ground stations or solar power plants.

During normal OGS or solar power plant operation, a local network of ISMs surrounding the facility allows the optimisation of operations by providing precise weather and atmospheric conditions nowcasting.
