Design and specify satellite navigation payload systems, document requirements and interfaces, coordinate external contractors, manage development progress, and assess system risks and quality.
About this role
This engineering role supports satellite development by evaluating GNSS receivers used for orbit and time determination in LEO-PNT and LNSS. It covers receiver verification, payload-system integration, and in-house development of receivers for ground user terminals.
The engineer defines receiver requirements and specifications, coordinates with external contractors, evaluates GPS, Galileo and QZSS across multiple constellations and frequencies, and analyzes pseudorange, carrier-phase and Doppler observables, including C/N0, multipath and cycle slips. The work includes GNSS-simulator testing, timekeeping-system interface design, integration tests, signal-processing algorithms and software-defined receiver implementation, using Python or MATLAB, Linux or Windows, RF instruments and Git.
No formal degree, years-of-experience, or other qualification threshold is stated. The posting says that much technical and company communication is in Japanese and that international members should be willing to learn Japanese and communicate across language barriers.
