Monitor-E ( Russian Монитор-Э , E stands for e xperimentell) is the name of a planned series of optoelectronic Russian earth observation satellites that are being built near Moscow by the company GKNPZ Khrunichev . The satellites are based on a "Jachta" satellite platform ( Russian Яхта ) developed by Khrunichev , which can be used for various satellites and consists of two 1,200 × 600 mm modules - a universal functional module and a payload module. The functional module of a Monitor-E weighs 420 kg, the payload module 330 kg, the total mass of the satellite is 750 kg. The satellites have ion thrusters to correct their position . The service life should be around five years.

The payload of the first satellite series Monitor E1 consists of a panchromatic (PSA, Russian ПСА = abbr. Of панхроматическая съемочная аппаратура) and a multi-spectral (RDSA, Russian РДСА = abbr. Of съемочная аппаратура распределенного доступа) optoelectronic cameras with resolutions of eight Meters and 20 meters. The PSA camera records a 96 km and RDSA a 160 km wide strip. The satellite was on 26 August 2005 with a Rockot KM - launcher in a 524-544 km high polar sun-synchronous orbit from the Plesetsk launch into space. After the successful launch in orbit, the control center initially lost contact with the satellite, but was able to bring it back under control a few hours later. On October 18, 2005, the control center again lost contact with Monitor-E1 after problems on board the satellite put it in a non-oriented position. Although it was possible to regain contact soon afterwards, attempts to regain full control of the satellite initially failed. The first deployment of the Earth observation payload took place on November 26th and was successful.

The cost of developing and manufacturing the Monitor E1 satellite is given at 1.95 billion rubles (the equivalent of around 60 million euros ). Monitor-E1 was funded 30% by the Russian space agency Roskosmos and 70% by Khrunichev. In return, Roscosmos received the rights to 70% of the satellite's images, and Khrunichev can freely dispose of the remaining 30%. The satellite is also the first operational use of the Jachta platform. Khrunichev built appropriate facilities specifically to control the Monitor E1 satellite and to evaluate and archive the data received.

In addition to the Monitor-E series, Khrunichev is also planning other satellite series: Monitor-I, Monitor-S and Monitor-O for optoelectronic earth observation and Monitor-R3 and Monitor-R23 for radar-based earth observation. To what extent these plans will be implemented is still unknown.
