<strong>The</strong> practice <strong>of</strong> the remote sensing <strong>of</strong> the <strong>Earth</strong> shows that the<br />
traditional in-flight monitoring techniques do not assure the required<br />
long-term stability.<br />
Approaches to problem solution<br />
• Develop and use onboard sources based upon phase transition <strong>of</strong><br />
substances.<br />
Studies are required to<br />
- select suitable substances,<br />
- determine their properties under the space environment<br />
- design onboard sources.<br />
• Develop a space-borne radiometric calibration facility<br />
