Encrypted GPS M-Code: It’s Here, and It’s Critical

August 01, 2021 15:57 - 12 minutes - 22.3 MB

Global Navigation Satellite Systems (GNSS), particularly the US Global Positioning System (GPS), are an ever-present feature of modern life. However, they provide much more than simply the positional information that most people associate them with, and which anyone with a GPS-enabled smartphone is aware of.

NTP vs. SNTP: What’s the Difference?

July 08, 2021 12:06 - 5 minutes - 9.81 MB

(And Which One Do You Really Need?) NTP (Network Time Protocol) and SNTP (Simple Network Time Protocol) are similar TCP/IP protocols in that they use the same time packet from a Time Server message to compute accurate time. The procedure used by the Time Server to assemble and send out a time stamp is exactly the same whether NTP (i.e., full implementation NTP) is used, or SNTP is used.
