Passive Microwave vs SAR sea ice: The Ultimate Guide to Real-Time Arctic Sea-Ice Mapping
Passive Microwave vs SAR sea ice: Which sensor prevents maritime disasters? We analyze the trade-offs between AMSR2 coverage and Sentinel-1 precision for 2025 real-time mapping. Imagine navigating a liquid natural gas (LNG) tanker through the Northern Sea Route in total darkness. It is polar winter. Optical satellites are useless because there is no sunlight, and…

Satellite Tech 101: Part 2 – Seeing in the Dark with SAR (Sentinel-1 & ICEYE)
Optical cameras can’t see through clouds. In Part 2, we explore Synthetic Aperture Radar (SAR), the LEO technology that allows satellites like Sentinel-1 and ICEYE to image the Earth at night and through storms. In Part 1 of this series, we introduced the “Speed Demons” of the satellite world: Low Earth Orbit (LEO) satellites. We…
