Zahavan Imperial Astrologia Ministerium

The Zahavan Imperial Astrologia Ministerium (ZIAM) is a ministry of the Zahavan government, under the Intellegentius Administratum which directs most of its operations. Its primary purpose is to design, build, launch, and operate the for the Imperial government. Additionally ZIAM has several departments dedicated to, research, and.

Directives
The main directive of the Zahavan Imperial Astrologia Ministerium is the development, construction, and maintenance of reconnaissance satellites and their support systems for the Imperial government. More recently increased attention has been given to space exploration and other civilian applications. Further following ratification by the ECOSEAS governing council in 2019, ZIAM has begun sharing of intelligence reports and data, gathered via its satellite network with ECOSEAS allies, following the information's approval of release by the Intellegentius Administratum.

Radar
The first modern Imperial radar was invented and developed at ZIAM's Electronic Applications and Research Laboratory in Arcanium in 1924. By 1937, EARL installed the first operational radar aboard the INV Helictus. EARL then further developed over-the-horizon radar as well as radar data displays. EARL's Radar Division continues important research & development contributing to Imperial Navy and Imperial armed forces capabilities.

Meteorology
The ZIAM facility located on the isle of Cretacia called Site-C contributes to weather forecasting in the Imperium and around the world by publishing imagery from 18 weather satellites. Satellite images of severe weather (e.g. hurricanes and cyclones) that are used for advanced warning often originate from this facility. Site-C also publishes weather forecasting models including predicted hurricane and cyclone tracks in the Iapetus ocean and all along the eastern Avalonian coast.

Military Satellites
The ZIAM military and intelligence directorates maintain five main satellite constellations:
 * ZIAM SIGINT constellation
 * ZIAM GEOINT constellation
 * ZIAM Communications Relay constellation
 * ZIAM Reconnaissance constellation
 * ZIAM Global Positioning constellation

The ZIAM Global Positioning constellation known as PYREMIUS was developed and deployed initially to cover only the Avalonian continent, in the even hostilities between the Imperium, and North-South Concordant members or their allies broke out the Zahavan General Staff decided the potential loss, or denial of use of NSC existing GPS constellation assets would be unacceptable and leave the Imperium's military severely handicapped. By mid 2020 PYREMIUS is expected to achieve global coverage, and while capable of operating independently is also able to coordinate with existing GPS constellations to provide more accurate positioning information to users.

 * Karceri satellites that monitor for ballistic missile launches and nuclear detonations
 * Skopos I-IV family of satellites, with the IV bloc of satellites being launched in 2016 providing optical imagery
 * Prospicio family of satellites. First entered service in 1990.
