802.11 baseband implementation decoding beacon packets

Beacon packets are sent by the access point in a BSS (or its equivalent in an IBSS) to announce the beginning of a Contention Free period (CF), during which the right to transmit is conferred by the access point by polling. Beacon management packets carry BSS timestamps to help synchronize member stations with the BSS, and other information to help them locate and choose the BSS with the best signal and availability.

cardboard box 2.4 GHz horn/waveguide antenna (to be rescaled for hydrogen line 1200-1700 MHz)

Connectivity for the SSRP is provided by a USB 2.0 (480Mbps) interface board based on the Cypress Semiconductor CY7C68013 EZ-USB FX2. This board is an off the self part available from ELRASoft for $89. The FX2 is well suited for high speed data transfers; the chip itself supports the full 480Mbps USB 2.0 bandwidth and provides a versatile FIFO-buffered 16bit parallel data interface.

SECD is an abstract machine invented by Peter J. Landin which has been used as a basis for various implementations of functional programming languages. It has traditionally been implemented in software…

oswald's dataviz summary - octave, gps and visualisation

The most important NMEA sentences include the GGA which provides the current Fix data, the RMC which provides the minimum gps sentences information, and the GSA which provides the Satellite status data.
