VanZyl-1

VanZyl-1 (VZ-1) is Hydrosat's first pathfinder mission. Launched in August 2024 on the SpaceX Transporter-11 rideshare, VZ-1 is a technology demonstration and proof of concept for our forthcoming constellation that will redefine space-based thermal infrared remote sensing by enabling daily continuous monitoring of any location on Earth.

VZ-1 hosts two imaging payloads: Hydrosat’s first-generation, proprietary Longwave InfraRed Imager (LIRI) along with its Visible and near-InfraRed Imager (VIRI). LIRI acquires thermal infrared (TIR) imagery at wavelengths between 10.6 and 12.51 micrometers. VIRI images in 7 spectral bands ranging from 458 to 900 nanometers. VZ-1 imagery is acquired mid-morning local time.

VanZyl-2

Hydrosat's second pathfinder mission, VZ-2, launched in June 2025 on the SpaceX Transporter-14 rideshare. VZ-2 hosts the same two sensors as VZ-1, but acquires imagery in mid-afternoon local time.
