CSDA Vendor – Orbital Sidekick

NASA’s Commercial Satellite Data Acquisition (CSDA) program has acquired commercial datasets from Orbital Sidekick.

Imagem do artigo

Orbital Sidekick, Inc. operates a three-satellite constellation carrying identical hyperspectral instruments that deliver high-resolution (8-meter) hyperspectral imagery across 472 spectral bands to support a range of Earth science applications, including the detailed analysis of biodiversity, ecosystem health, and surface geology; greenhouse gas detection; and detecting solid chemicals related to pollutants. Each satellite is designed with a maximum off-nadir pointing angle of 25 degrees, which expands the accessible ground swath and enables flexible tasking. When operating individually, each satellite provides regular revisit opportunities across mid- and low-latitude regions. When operated as a three-satellite constellation, the revisit rates increase, particularly at higher latitudes, where overlapping orbital tracks provide enhanced temporal coverage. This capability allows users to receive frequent, daylight-consistent revisits around the globe to support the monitoring of both broad-areas and specific areas of interest.

GHOSt Satellites

SpecificationDescription
Sensor TypeSpaceborne hyperspectral imaging sensor
Spectral CoverageFull VNIRSWIR
Spectral Range400 – 2500 nm (VNIR & SWIR, including methane absorption features and vegetation red-edge)
Spectral Bands472 bands
Spectral Bandwidth~10 nm FWHM
Native Spatial Resolution~8.3 m Ground Sample Distance (GSD)
Delivered Spatial Resolution10 m GSD (downsampled per NOAA license requirements for data, not derived products)
Geometric Accuracy< 20 meters (post-geocorrection)
Imaging ModeLinescan1 (Pushbroom hyperspectral)
Collection TypeTasked satellite collections
Off-Nadir Capability±25°
Minimum Area Collection~4.3 km × 12 km (swath × along-track)
Maximum Along-Track CoverageUp to ~ 60 km per collection
1Linescan Mode: Uses the full 512-pixel width while slewing the satellite to match ground speed, maintaining square pixels (~8m × 8m). Supports both along-track and cross-track (E-W or W-E) collections. These additional collection geometries reduce the number of collections needed to cover a target due to increased swath and multi-directional capabilities. Offers high SNR and efficient area coverage.

Authorized Data Use and Users

Access to this data is governed by the CSDA End User License Agreements (EULAs). The minimum access level for data is the USG license. Depending on the specific data products provided, some or all data may also be available under higher-tier CSDA licenses, including USG-Plus and Public licenses.

Under the applicable license tier, authorized users may include:

  • U.S. Government federal employees
  • State, local, territorial, and tribal government personnel
  • U.S. Government contractors and subcontractors
  • U.S. Government–funded researchers and academic partners
  • Other users authorized under applicable CSDA license levels (USG, USG-Plus, or Public)

All data use must comply with the terms of the EULA. All data requests must be reviewed and approved by NASA’s Commercial Satellite Data Acquisition (CSDA) program.
