In addition to the HSRS infrared camera system, the BIROS small satellite also has other devices for experiments on further developing on-board technology.
DLR (CC-BY 3.0).
BIROS is the second satellite of the FireBIRD mission. The main payload is a highly sensitive infrared camera system equipped with 'fire magnifiers' that, like its 'brother' satellite TET-1, can be used as an early fire warning system and for climate research from space.
The BIROS satellite (Bispectral InfraRed Optical System) is the second of the FireBIRD satellites launched in July 2016. It is not a straightforward replica of its four-year-old 'brother' TET-1, but rather represents a new stage in the process of continuous development. Small satellites not only serve the purpose of Earth observation, but also the progress being made in this kind of technology.
BIROS has a greater payload than its counterpart when comparing the total mass of the satellites. While TET-1 components made up 42 percent the satellite, BIROS components have been increased to 46 percent. More payload means the acquisition of more scientific data, allowing for the early detection of fires for instance and, with that, higher economic efficiency in Earth observation missions from space, as well as the development of a system that improves remote sensing from space that can also be used in climate research.
BIROS has also been equipped with a new cold gas propulsion system that it will test. This system enables manoeuvres to be carried out whilst in orbit, so that the satellite's orbital position can be actively changed. Newly designed reaction wheels (High Torque Wheels) built into the satellites allow for the infrared cameras to be quickly and accurately positioned. These two capabilities make it possible to repeatedly capture data from the same region or area of Earth's surface, but from different angles.
Internal data processing and communication with Earth have also been greatly improved. A completely new on-board computer allows BIROS to process data at a speed that was unimaginable for former small satellites. The orbiter can then send its data to Earth via an optical (laser) downlink at a speed of up to one gigabyte per second. A separate modem can be used to send text messages about the parameters of detected fires directly to mobile devices in almost real time.
Further technology experiments on BIROS
In addition to cold gas propulsion, a laser communication system, and High Torque Wheels, BIROS is equipped with other experiments:
BIROS successfully released BEESAT-4 on 9th September 2016. The first one on earth who received the beacon signal from the picosatellite was an amateur radio operator in Brasil:
Operation and finance
BIROS, just like TET-1, will also be operated and monitored from the German Space Operations Center (GSOC) in Oberpfaffenhofen, and the German Remote Sensing Data Center (DFD) with its antenna facilities in Neustrelitz. The development, construction and operation will be funded by DLR. The German Federal Ministry of Education and Research (BMBF) will also support construction by contributing 5 million Euros.
