Inside Unmanned Systems and microdrones will host a free web seminar, “Part 107 Rule: Impact on Key Application Segments in the Commercial Drone Market,” on Wednesday, September 28, 2016 at noon EDT.
The initial discussion will focus on the implications of the Federal Aviation Administration (FAA) Part 107 rule on unmanned aerial systems (UAS) for mapping, surveying, and inspection applications, but anyone interested in using drones for commercial purposes is welcome to participate.
By Inside GNSSHow do you win when you are really losing?
Play a different game, move the goalposts, change the rules.
For several years now, a series of would-be wireless broadband service providers have been attempting to convince the Federal Communications Commission (FCC) to repurpose radio frequency spectrum near the GPS L1 band.
Past efforts have failed because of the transmissions’ demonstrated harmful effects on GPS and other GNSS signals. Now a new contender is trying to gain FCC’s approval by changing the way that those effects are measured.

GNSS event that most signified to you that GNSS had ‘arrived’
Testing of the initial handheld units from vendors such as Trimble’s two-channel GPS receiver and Rockwell Collins’ PLGR. “We thought, ‘What an amazing capability to have a handheld device that all you had to do was turn it on and it told you where you were – wow!’”

A cooperative network of government labs, funded by a hopeful broadband company, is now testing GPS receivers in a surprise program that will draw key federal agencies directly into an argument over GPS interference standards.

EquationsThe Galileo E6 signal is centered at 1278.75 MHz, and comprises three signals: an authorized signal (E6A, the publicly regulated service, PRS plus two civilian signals), a data component (E6B), and a pilot component (E6C). Both E6B and C are modulated using binary-phase shift keying (BPSK) code division multiple access (CDMA) memory codes, having lengths of 5,115 chips and chipping rates of 5.115 Mcps.
