StriX sees the ground through the clouds with a space radar
StriX observes the Earth despite the night and the clouds. This is the operation of Synspective's twelfth radar satellite, its uses and limitations.
An optical camera loses much of its usefulness when night falls or clouds hide the ground. A radar satellite can instead send its own waves to Earth and measure their return.
The Japanese company Synspective deployed its twelfth StriX satellite on 19 September 2026. Placed in low-Earth orbit by a Rocket Lab Electron rocket, it must strengthen a constellation aimed, inter alia, at monitoring disasters and infrastructure.
The launch is successful, but the satellite is not yet in service. Synspective foresees several months of testing and commissioning before using its observations commercially.
A radar rather than a camera
StriX uses a synthetic aperture radar, or SAR. The satellite emits microwaves to the ground, then analyzes the reflected signal during its orbital displacement. The treatment combines several measures to simulate a much larger antenna.
This method works day and night. Its waves also cross clouds, smoke or rain better than visible light.
The result does not necessarily look like a photograph. The return depends in particular on the roughness, humidity and orientation of the surfaces; Its interpretation therefore requires treatment.
According to the [Synopsis Technical Sheet] (https://www.synspective.com/satellite/satellite-strix/), StriX belongs to the 100 kg category. Its housing measures about 0.8 × 1 × 0.8 m before the deployment of an antenna of 5 × 0.8 m.
The radar operates in the X-band around 9.65 GHz, observing on both sides of its trajectory. Its planned mission lasts about five years. These characteristics come from the manufacturer.
The twelfth satellite is in orbit, not yet operational
The "Owl By The Dozen" mission took off from the Māhia Peninsula in New Zealand on 19 September at 0322 UTC. Electron placed StriX in an orbit of approximately 572 km near 53 minutes later, according to [Space.com] (https://www.space.com/space-exploration/launches-spacecraft/rocket-lab-electron-owl-by-the-dozen-launch).
Synspective confirmed that the satellite had reached orbit and deployed its antenna. His [official release](https://www.synspective.com/news/12th launch/) indicates, however, that testing and calibration will take several months.
The launch therefore does not yet confirm the quality of the images, the stability of the radar or the transmission rate. These elements must be validated before entry into service.
Why multiply small satellites?
A satellite does not continually fly over the same place. Several orbital planes can shorten the wait between two observations and compare changes more quickly.
Synspective targets over 30 satellites in the second half of the decade. Twelve successful launches, however, do not mean that the twelve aircraft are simultaneously operational or that almost instant global coverage already exists.
The company claims that StriX costs about 20 times less to develop and launch than a large conventional SAR satellite. This comparison is not accompanied by an absolute cost or an independent methodology.
Its small size also imposes energy, radar power and transmission compromises. A large fleet requires repeated launches and replacement of end-of-life aircraft.
Concrete but not automatic uses
After flooding or earthquakes, radar can map hard-to-reach areas despite clouds. Images taken at different times may also reveal a shift of the ground near a road, dam or site.
The applications announced include monitoring of damage, forests, infrastructure and marine facilities. To detect a change does not reveal the cause; a ground check may remain necessary.
Synspective also announced on 15 September the programme [OMNIA](https://www.synspective.com/news/synspective omnia/). Governments or companies could set aside a priority observation capacity without financing a complete constellation alone.
OMNIA provides a separate constellation. No full calendar, first customer or public price was communicated; This capacity is therefore not yet built.
Prices and availability in Canada
Synspective does not publish a fee schedule for StriX images, analyses or the OMNIA program. Clients must request a commercial proposal.
No partners, government contract or reception station in Canada were announced for the twelfth satellite.
The price may vary depending on the area, resolution, frequency of observation, priority, delivery time, analysis, license of use and contract. No reliable Canadian dollar range is available.
Limits or Considerations
StriX does not literally see through all the materials. The radar crosses some clouds and precipitation, but its signal interacts with vegetation, water, terrain and buildings.
The resolution, frequency of review and speed of delivery depend on orbit, imaging mode, competing demands, ground stations and processing.
Security uses also raise issues of confidentiality, data control and priority access. Finally, Synspective will have to manage the risks of breakdown, orbital debris and replacement of an increasing constellation.
Conclusion
The twelfth StriX makes the radar constellation of Synspective more concrete. His interest is less in a spectacular image than in the ability to regularly compare the ground despite the darkness and the weather.
The next step will be to demonstrate that this new satellite provides reliable data after it is put into service and that the addition of devices actually reduces the time between observations.
