Each GHOSt satellite features a proprietary hyperspectral imager manufactured by OSK. The sensor is developed to capture 512 spectral bands across the visible (VIS) to shortwave infrared (SWIR) region. The enhanced monitoring provided by these imagers will enable GHOSt to produce the highest resolution commercial hyperspectral imagery launched to-date. Some key applications include capturing critical environmental and situational awareness information for defence, detecting minute real-time changes in physical infrastructure, monitoring energy infrastructure and regulatory compliance, detecting environmental erosion and degradation, and monitoring crop yield and agriculture.

Monochromatic light is a type of light that consists of a single wavelength or frequency. It has a number of advantages over other types of light, including precision, intensity, and directionality. However, it also has some disadvantages, including cost, complexity, and safety. Monochromatic light is used in a variety of applications, including scientific research, medical applications, industrial applications, and entertainment.

"Persistent, hyperspectral imaging is a critical new capability in remote sensing," said Chris Biddy, Co-founder and CEO of Astro Digital. "We are very pleased to be supporting Orbital Sidekick's mission with our proven satellite technology and capabilities."

GHOSt aims to provide enhanced hyperspectral imagery for use in industrial, government, agriculture, environmental and defence sectors. Specific key applications of its use include capturing critical environmental and situational awareness information for defence, detecting minute real-time changes in physical infrastructure, monitoring energy infrastructure and regulatory compliance, detecting environmental erosion and degradation, and monitoring crop yield and agriculture.

Developed by Astro Digital, each of the GHOSt satellites have a mass of 91.4 kg and a planned total in-orbit lifetime of just over 5 years. The spacecraft are based on the flight-proven Corvus-XL smallsat platform and utilise Astro Digital’s heritage flight computer, attitude determination and control subsystem (AOCS), power and communications subsystems. Payload data downlink is to be conducted via Ka-band, in addition to S-band for high speed data (HSD) transmissions.

Monochromatic light is light that consists of a single wavelength or frequency. This type of light is often produced by lasers or other specialized light sources. Monochromatic light is used in a variety of applications, including spectroscopy, microscopy, and laser surgery.

In addition OSK is looking to utilise the 2025-2110 MHz S-band for Telemetry, Tracking, and Command (TT&C), as well as modulation and coding of the high speed data (HSD) link for payload transmissions. Specifically, OSK plans to use the 2045.0-2050.0 MHz band for the HSD control uplink. This technique adjusts the satellite’s modulation and coding to optimise payload downlink conditions, ensure proper link performance and efficiency, and advise the spacecraft to retransmit any lost data frames. A second link, operating within the 2054.85-2055.15 MHz band, will provide the traditional TT&C uplink operations for the GHOSt satellites.

Maverick Space Systems will provide mission integration hardware and services to launch GHOSt on SpaceX's Falcon 9 at the end of this year and continuing into 2022. "Taking advantage of frequent low-cost launch opportunities is critical to achieve Orbital Sidekick's constellation. We are excited to partner with them and further reduce their per-satellite launch costs by aggregating two GHOSt satellites per ESPA port," said Roland Coelho, CEO of Maverick Space.

OSK plans to use a space-to-space L-band intersatellite link between its GHOSt satellites and the existing commercial Globalstar NGSO constellation. The GHOSt satellites will transmit to Globalstar satellites, pursuant to an agreement with Globalstar, but will not have the capability to receive communications from the Globalstar satellites.

Monochromatic light has a number of advantages over polychromatic light. For example, monochromatic light is more easily focused and can be used to create sharper images. Monochromatic light is also less likely to cause chromatic aberration, which is a distortion of the image caused by the different wavelengths of light being focused at different points.

With the first satellites launched on 15 April 2023, Global Hyperspectral Observation Satellite (GHOSt) is a constellation of six technically identical hyperspectral imaging microsatellites by Orbital Sidekick Inc. (OSK). GHOSt aims to build on its predecessor Aurora to provide enhanced commercial data sets used in industrial, government, agriculture, environmental and defence sectors.
