CubeSats Require Special ESD Handling Protocols for Launch Integrity — Part I
Figure 1: Tu-Pod in Space (Courtesy Amin Djamshidpour, Co-Founder Teton Aerospace) CubeSats are relatively inexpensive when compared to traditional vehicle-size satellites. Since their inception, CubeSat spacecraft have shown functional success rates ranging from 40% to 75% for launch and deployment phases. According to the International Journal of Aerospace Engineering, … [Read more...]
An Easy Way to Calculate a Microwave Wavelength in Inches
A colleague, Mike Stasiowski, and I came up with this quick GHz wavelength formula while designing quad ridge circular polarized jamming antennas for the military when working at Nurad. The textbook formula (wavelength = c/f) where: c = the speed of light 3.00×108 m/s, and f = frequency in Hz, was cumbersome at times to calculate, then convert, to inches for practical … [Read more...]
