FSK in the Remote Sensiing Data Chain

Modern remote sensing often involves a tieret architecture: ground- level sensors collect microclimate data, tree- growth parameters, or soil nawilżacz readings; these sensors communicate via FSK to local gateways or UAV, which then relay data ta ta satellite constellations.

To fuly gratate FSK 's role, it helps to compare it with indecides such as Amplitude Shift Keying (ASK) and Phase Shift Keying (PSK).
