Ground Based Sensors (U)

(U) These systems are ground-based space environmental monitoring sensors that are either operational, in development, or being studied. Accurate, timely space environmental data are required to support missions such as missile warning, space surveillance, and satellite operations. There's currently a requirement for scintillation forecast products to support MILSATCOM users. Scintillation degrades radio frequency signals which results in either noisy voice communications and errors in data transmissions, or no communications at all. Scintillation is a naturally-occurring phenomenon that's more disruptive during specific times of the day. It tends to be more prevalent in the hours just before sunset and in the equatorial region, but can disrupt communications globally. Disturbed ionospheric conditions and scintillation can inhibit the ability to discriminate between warheads and decoys and can interfere with satellite communications and navigation. Geomagnetic storms can cause false launch indications and affect satellite tracking efforts. The 50th Weather Squadron requires data at frequent intervals and in near-real-time to meet mission requirements using their specification and forecast models.
