"The absence of Canadian geodetic observatories has direct consequences for its own space program. #radarsat, once a symbol of Canadian leadership in space, is today the only major commercial synthetic aperture radar mission not supported by the International Laser Ranging Service." - Anusuya Datta

I had a giggle at some of those suggestions.
➡️ It is a (trihedral) CORNER REFLECTOR, made of three plates forming a corner. It is used for calibrating SAR satellite systems (in our case, RADARSAT). Its design provides a strong, predictable reflection that is not sensitive to its orientation.

Canada’s satellites monitor Earth’s climate, land, and ecosystems while supporting space research. Technologies like RADARSAT and SCISAT allow us to protect habitats, study geodiversity, and prepare for challenges in a changing world. 2/3

I don’t remember that one. I did write some software to talk to the SPOT and RADARSAT satellites in the 90s though, probably not related 🤓

Fortunately, we have the technology, especially in radar imaging satellites, and a commercial sector, including the Canadian company MDA Space, that can deliver. MDA built the RADARSAT Constellation Mission satellites, among the most advanced in the world.

...Or more complex if use thickness of actual ice, excluding open water.
Thickness is hard to measure (therefore so is volume). It is now measured by radarsat probing, but that's tricky because of snow cover, aot.
Real-time thickness and volume series, including this one, are from tracking models.

We got to develop kick ass air defence. We have excellent radar technology: Radarsat II and the CHIME telescope for examples. We make commercial quantum computers. We can collaborate with Europe on the missile part. We have the talents. We have what it takes for innovative solutions.

Why not? We've been a Cooperating State within the European Space Agency since 1979.
I remember there being ESA posters scattered around the office at RADARSAT when I did three co-op work terms there in the late 80s. (I may even have a few still stashed away.)

I'm way out of my depth here, so take these as the ignorant ravings that they are, but off the top of my head:
* A CSA with dozens of radarsat-like programs
* A CanmetMATERIALS unit focused on construction in permafrost
* A Grain Research Laboratory empowered by a mandate beyond quality and safety.
