Push broom camera questions: resolution, coverage, and ordering
This FAQ answers practical questions about the 0.75m-resolution Push-broom camera, including its imaging method, resolution, spectral bands, swath width, physical size, power, weight, data rate, and stated delivery timeframe.
The 0.75m-resolution Push-broom camera is designed for optical remote sensing from a 535 km orbit. Its specifications cover image resolution, coverage, spectral bands, physical integration, and data handling.
What is the resolution of this push broom camera?
The camera has a resolution of 0.75 m. It uses push-broom imaging and a coaxial folding optical system. At a 535 km orbit, it can obtain high-resolution images at 0.75 m resolution.
How much area can it cover, and which spectral bands does it support?
The swath width at nadir is at least 17 km. The camera supports panchromatic and multispectral coverage:
- Panchromatic: 450 to 700 nm
- Blue: 430 to 510 nm
- Green: 510 to 580 nm
- Red: 630 to 690 nm
- Near-infrared: 740 to 895 nm
These bands give procurement teams a clear basis for checking compatibility with the planned remote-sensing payload and downstream image-processing workflow.
What are the camera’s main physical and electrical specifications?
The camera has a diameter of 440 mm and a length of 710 mm. Its power consumption is 85 W, its weight is 10 kg, and its data rate is 2.13 Gbps. The signal-to-noise ratio is 38 dB.
For payload integration, check the available volume against the Φ440 mm × 710 mm envelope and confirm that the platform can accommodate the 85 W power demand and 2.13 Gbps data rate.
How long does the push broom camera take to complete and deliver?
The stated earliest completion and delivery period is 10 months. Buyers should send the required payload configuration, interface details, and quantity when requesting a project schedule from Astralink Science and Technology Co., Ltd.
