Development and Characterization of Microsatellite Genetic Markers for Hyalomma rufipes, a Tick Vector of Crimean‐Congo Hemorrhagic Fever Virus

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study developed and validated 14 polymorphic microsatellite markers to investigate the population genetics of Hyalomma rufipes, a tick species that transmits Crimean‐Congo Hemorrhagic Fever Virus (CCHFV) in East Africa. Ticks collected from livestock in northern Kenya were morphologically and genetically identified, followed by genome sequencing ...

Estimating the Orbital Parameters of a Nanosatellite When Measuring the Total Electron Content in the Ionosphere Based on the Retransmission of GPS Navigation Signals

Доклады Белорусского государственного университета информатики и радиоэлектроники
A method for estimating the orbital parameters of a nanosatellite-relay, implemented by measuring the total electron content in the ionosphere based on relaying GPS navigation signals at frequencies of 150/400 MHz, is substantiated.

Communication Subsystem for PilsenCUBE Nanosatellite [PDF]

2018 International Conference on Applied Electronics (AE), 2018
This paper presents a design concept of new radio communication subsystem, intended for use on the PilsenCUBE nanosatellite. The hardware and software solution is based on previous experiences with the VZLUSAT-1 setup and operation. Our aim is to overcome weak points which were found, use modern powerful components actually available and build reliable
