Start with your own requirements

Before comparing data sheets, write down your mission constraints:

• Required ground detail. What is the smallest feature you need to see in the imagery?
• Area coverage per pass. Do you need fine detail over a narrow strip, or wide coverage over large regions?
• Spectral needs. Are panchromatic and visible/near-infrared bands enough, or do you need short-wave, mid-wave or long-wave infrared?
• Imaging modes. Is push-broom imaging enough, or do you also need inertial space, night-time or video imaging?
• Platform mass. How does weight affect your launch and integration planning?
• Operational workflow. Do you need on-board tasking and fast data return?

Your answers decide which criteria below matter most.

Published specifications

This satellite offers independent on-satellite mission planning, real-time data transmission and on-satellite AI. Combined with fast maneuvering control, it can perform single-orbit multi-point target imaging with fast information return. It has high resolution, high integration and intelligence.

Note: the 0.5m figure is stated for full-color imagery. The materials do not give a separate resolution for the multispectral bands, so ask the supplier to confirm it if multispectral detail matters to you.

How it compares with other documented Astralink satellites

The same product materials describe two other satellites. This comparison helps show where the 0.5m option fits.

What the comparison shows:

• For the finest ground detail, the 0.5m model is the choice.
• For a wider swath at sub-meter resolution, the published 0.75m configurations list swaths of 17km, 18km or 40km, against 15km for the 0.5m model.
• For a lighter platform, two 0.75m configurations are listed at about 40kg and about 20kg, compared with about 90kg.
• For video imaging or inertial space imaging, those modes appear in the 0.75m and 5m materials, not in the 0.5m specification.
• For infrared, night-time imaging or very wide area coverage, the 5m-Resolution Spectral Satellite, with its 110km swath and infrared loads, is the better-documented fit. No infrared bands beyond near-infrared are listed for the 0.5m model.

When this option may not apply

The 0.5m-Resolution Satellite is probably not the right recommendation if your mission needs:

• Thermal or short/mid/long-wave infrared imaging
• Night-time imaging or video imaging
• Swath widths well beyond 15km per pass
• The lowest possible platform mass

Questions to confirm with the supplier

• Pricing, lead time and delivery terms
• Certifications, test reports and qualification documents
• Multispectral band resolution and other performance figures not shown above
• Customization options, launch and integration support, and data service arrangements
• Export compliance and availability for your country or region

This guide does not make any claims about these points.

Summary

This satellite suits buyers who put fine panchromatic detail first and value on-board mission planning, real-time data transmission and on-satellite AI, and who can accept a 15km swath and push-broom-only imaging. If wider coverage, lighter mass, video or infrared capability matters more, compare the 0.75m and 5m options with your own requirements.
