History and Development
Origins and Concept
The concept for Clear Choice Satellite emerged from a collaboration between Clear Choice Technologies and a consortium of universities and research institutions focused on sustainable agriculture and environmental stewardship. In 2018, a feasibility study was commissioned to evaluate the technical and economic viability of a mid‑cost, high‑resolution Earth observation satellite. The study concluded that leveraging existing commercial off‑the‑shelf (COTS) components, coupled with a lean development schedule, could reduce launch costs by approximately 30% relative to comparable platforms.
During the conceptual phase, the project team identified key requirements: a spatial resolution of 2 meters in the visible spectrum, revisit times of less than three days over the continental United States, and the ability to support both real‑time data streaming and on‑board data processing. These specifications were chosen to enable timely decision support for sectors such as agriculture, forestry, and emergency management.
Design and Construction
The satellite bus was built on the Clear Choice CubeSat platform, a 6U modular architecture that supports a variety of payloads. The design emphasized reusability and rapid prototyping. Key design elements include:
- Structural frame: Aluminum alloy with carbon‑fiber reinforcement to achieve a mass ratio of 0.5 kg/m².
- Power system: 5 kW solar array with silicon heterojunction cells and 10 kWh lithium‑ion battery bank.
- Thermal control: Passive radiators supplemented by active heaters to maintain instrument temperature within ±5°C.
- Attitude control: Three‑axis stabilized platform utilizing reaction wheels and magnetorquers, achieving pointing accuracy better than 0.1 arcseconds.
The payload suite comprises a multispectral imager, a LiDAR system, and a data handling unit capable of compressing and routing data to ground stations. The imager, built by SpectroTech, provides seven spectral bands ranging from 0.4 µm to 1.1 µm, with a swath width of 30 km. The LiDAR, supplied by AeroScan, offers vertical resolution of 0.5 meters and coverage of 20 km across the swath.
Launch and Deployment
Clear Choice Satellite was integrated into a Falcon 9 Block 5 launch vehicle for its maiden flight. The launch took place on 12 September 2024 from Cape Canaveral Space Force Station, alongside a cluster of other small satellites. After launch, the satellite was transferred into a geostationary transfer orbit (GTO) and subsequently executed a series of apogee motor burns to reach a final geostationary orbit (GEO) at 35,786 km altitude above the equator.
The first on‑orbit commissioning phase involved power system verification, attitude control calibration, and instrument health checks. The imager achieved the specified spatial resolution during initial ground testing, while the LiDAR demonstrated accurate elevation measurements over test sites in Utah. Once commissioning was complete, the satellite entered its operational phase with a nominal mission life of 10 years.
Technical Specifications
Spacecraft Bus
Clear Choice Satellite utilizes a 6U CubeSat bus, enabling a compact footprint while accommodating multiple payloads. The bus architecture supports a maximum payload mass of 40 kg, with a total mass of 250 kg including structure, power, and attitude control systems. The satellite’s power budget is 5 kW during daytime operations, with an average power consumption of 1.8 kW for payload and subsystems.
Propulsion System
The satellite is equipped with a xenon ion propulsion module providing precise station‑keeping capability. The ion thruster delivers 0.2 N of thrust with a specific impulse of 4,000 s, sufficient to maintain GEO position within ±10 meters over the mission life. The propulsion system is powered by dedicated solar panels and a high‑capacity lithium‑ion battery pack, allowing continuous operation during orbital maneuvers.
Payload and Instruments
The imaging payload comprises two primary instruments: a multispectral imager and a LiDAR system.
- Multispectral Imager: Seven spectral bands (Blue, Green, Red, Red Edge, Near‑Infrared, Shortwave‑IR, Panchromatic) with spatial resolution ranging from 0.5 m (panchromatic) to 2 m (multispectral). Swath width of 30 km and ground sampling distance of 1.5 m for panchromatic images.
- LiDAR System: 1550 nm laser source with 500 mA current drive, producing a vertical resolution of 0.5 m and a horizontal resolution of 0.3 m. Swath coverage of 20 km, with data sampling rate of 10,000 points per second.
Both instruments are coupled with high‑speed data processors that perform real‑time compression (JPEG2000 for imagery, proprietary point cloud compression for LiDAR) before downlinking.
Power and Communications
Power generation is achieved through a 12 kW solar array, with a 10 kWh battery bank providing redundancy during eclipse periods. Communications rely on a dual‑band system: X‑band for high‑rate science data transmission and Ka‑band for low‑latency telemetry and command. The data rate for X‑band is 50 Mbps, while Ka‑band supports 200 Mbps, allowing near‑real‑time delivery of processed imagery to customer data centers.
Mission Objectives and Operations
Primary Mission Goals
Clear Choice Satellite was tasked with four primary objectives:
- Provide high‑resolution, multi‑spectral imagery to support agricultural monitoring, including crop health assessment and yield prediction.
- Deliver LiDAR data for land cover classification, forest canopy height estimation, and topographic mapping.
- Monitor atmospheric parameters such as aerosol optical depth, water vapor concentration, and cloud properties through auxiliary sensors.
- Support rapid response to natural disasters by supplying timely imagery for damage assessment and resource allocation.
Operational Profile
The satellite operates in a geostationary orbit, enabling continuous coverage of its assigned footprint. It follows a duty cycle that alternates between imaging and data downlink sessions, optimized to maximize revisit frequency. Each imaging cycle lasts approximately 12 minutes, followed by a 4‑minute downlink window. The satellite’s on‑board data processing units prioritize cloud‑free scenes, reducing the need for ground‑side post‑processing.
Ground operations are managed from a dedicated mission control center in Austin, Texas. The center handles scheduling, anomaly detection, and data distribution. Data products are made available to customers through secure web portals, with options for API integration for automated workflows.
