Welcome to my website.
On this site I publish posts and links about the topics that interest me. Those are science, astronomy, technology, radio astronomy, radio communications, receiving data from satellites, nature, space, simulator flying, specially Airbus A321 and many more. The content are in Finnish and also in English.

Airbus A321 – Simulento
Tule kokeilemaan minkälaista on lentää Airbus A321 matkustajalentokonetta. Simulaattori ei ole ns. “Full Flight Simulator”, eli se ei liiku. Ohjaamo jäljittelee oikeaa ohjaamoa ja sillä on mahdollista lentää missä päin maailmaa tahansa. Vaikka simulaattori ei ole virallisesti kelpuutettu harjoitteluun (Training Simulator), niin sillä voi myös harjoitella proseduureja, kuten Raw ILS ja VOR-laskeutumisia.
Simulaattori sijaitsee Helsingissä, lähellä Linnanmäen huvipuistoa. Simulaattori on hinnoittelultaan edullinen. Tervetuloa kokeilemaan!
L-Band Satellite Signal Exploration with RTL-SDR and Patch Antenna
Today I spent some time exploring the L-Band spectrum (1500-1700 MHz) using an RTL-SDR dongle connected to an L-Band satellite patch antenna on a Raspberry Pi. The setup is simple but effective for receiving various satellite signals including Inmarsat, Iridium, GPS, and COSPAS-SARSAT search and rescue transponders. Hardware Setup RTL-SDR with R820T tuner (RTL2838) L-Band patch antenna with LNA Bias-T enabled (+5V for LNA) Raspberry Pi [...]
Balcony antenna setup for VHF/UHF/SAT bands
My balcony antenna setup for VHF, UHF and SAT bands. I receive LEO-satellites on 145 MHz and on 437 MHz and undecoded traffic on Military Air band on 240-380 MHz. On L-band I receive Air Traffic ACARS-messages and ships STD-C messages and EGC/LES data traffic from Inmarsat(Alphasat) satellite. Every now and the I also listen radio amateurs working on QO-100 satellite on 10 GHz. Satellite dish diameter is 90 [...]
Radio signal from Soyuz spacecraft – Expedition 63
Astronaut Chris Cassidy of NASA and cosmonauts Anatoly Ivanishin and Ivan Vagner of the Russian space agency Roscosmos lifted off on board Soyuz spacecraft at 4:05 a.m. EDT from Baikonur Cosmodrome in Kazakhstan. They make a four-orbit and six-hour journey to the International Space Station. This is the third spaceflight for both Cassidy and Ivanishin and the first for Vagner. During their mission on the station, they'll welcome NASA's [...]
Milstar UHF FHSS Downlink
UHF FHSS Downlink of Milstar, a Unites States joint military service satellite communications system that provides secure, jam resistant, worldwide communications. Milstar (Military Strategic and Tactical Relay) is a constellation of military communications satellites in geosynchronous orbit. Those are operated by the United States Air Force and they provide secure jam-resistant worldwide communications so that they meet the requirements of the Armed Forces of the United States. Six spacecraft [...]
Receiving old Russian Military COSMOS Navigation Satellite Signal – Video
Receiving Cosmos 2463 satellite with SDR# software and SIRIO SD 1300 N Discone Antenna 25 MHz - 1.3 GHz antenna powered with amplifier. For satellites tracking I use Orbitron. Cosmos satellites are old Russian Navy navigation satellites that are no longer in use. See more information below. "The Russian Military Parus satellites are/where used for low-earth orbiting navigation information and store-dump radio communications relay service for Red Navy surface [...]
