Business Context
Advanced sensors can provide higher resolution, sensitivity, spectral coverage, measurement frequency, or detection accuracy. These improvements frequently require larger optics, additional detectors, higher power, more processing, greater data storage, and increased thermal-control capacity. Payload capability can therefore grow faster than the spacecraft resources available to support it.
Space TRIZ Resolution
Sensor capability should focus resources on information value rather than maximum performance across every observation. Adaptive sensing, variable resolution, selective activation, multisensor sharing, onboard target identification, and configurable observation modes can concentrate high-performance sensing where it produces the greatest mission benefit.
Applicable TRIZ Principles
Principle 3 – Local Quality applies maximum sensing capability selectively according to target value.
Principle 15 – Dynamics changes sensor configuration according to observation requirements.
Principle 23 – Feedback uses initial measurements to determine when additional sensing resources are justified.
Expected Outcome
Greater useful sensor capability
Lower average payload resource demand
Reduced unnecessary data generation
Improved observation efficiency
Decision Indicators
Early indicators include:
Sensor improvements require disproportionate spacecraft resource growth.
Maximum sensor performance is used for low-value observations.
Payload resource requirements determine overall spacecraft size.
Different targets receive identical sensing configurations.
Additional sensor data produces limited additional mission value.
