Satellite Sun Sensor Price

Satellite sun sensors serve as one of the core components that ensure precise spacecraft attitude and stability. They primarily detect the Sun’s position relative to the satellite and provide critical data for the Attitude Determination and Control System (ADCS). Therefore, sun sensors become standard equipment in over 80% of missions that require attitude control.

Factors That Affect Sun Sensor Prices

Accuracy and Resolution: Accuracy ranges from 5° to 0.1°. Each order-of-magnitude improvement doubles manufacturing difficulty and cost. Thus, fine sensors typically cost 50%–100% more than coarse ones.

Size and Mass: CubeSats remain extremely sensitive to every gram. Ultra-miniature designs under 1 gram demand high-end processes, so they naturally cost more.

Environmental Adaptability: Sensors must tolerate 10–60 krad radiation, operate from -45°C to +110°C, and withstand vibration and shock. These requirements significantly raise costs.

Flight Heritage and TRL Level: Mature TRL 9 products carry low risk and spread verification costs, so they often offer better price competitiveness.

Interfaces and Additional Functions: Digital interfaces, built-in magnetometers, and custom harnesses all increase expenses. Analog types stay cheapest, yet satellites need extra onboard processing.

Purchase Quantity and Discounts: Buyers secure much lower unit prices through bulk orders. University projects frequently receive 10%–20% academic discounts.

Suppliers and Export Controls: Asian and European vendors without ITAR restrictions (such as Tensor Tech and Solar MEMS) usually deliver clear price advantages over traditional U.S. manufacturers.

How to Purchase Satellite Sun Sensors at the Best Price?

Compare prices across multiple platforms and review the latest quotes and datasheets.

Request bulk quotes: the more units of the same model you buy, the lower the unit price becomes.

Apply for academic discounts: most manufacturers grant 10%–20% off to universities and research institutes.

Choose ITAR-free products: you avoid complex export licensing and receive faster delivery.

Use open-source solutions during prototyping: DIY options under $200 work well for ground tests, but flight models must remain space-grade.

Calculate total life-cycle costs, including integration, testing, shipping, and customs duties.
