Systems like GPS or GLONASS used simple trilateration to calculate positions based on the time it took for signals to travel between satellites and receivers. These models, while incredibly precise, were rigid and susceptible to the challenges of real-world environments: atmospheric interference, multipath effects, and signal degradation. But in recent years, something   revolutionary   has been...]]></description><link>https://saminnasrazadani.wixsite.com/saminnasr/post/ai-in-navigation-how-machine-learning-is-changing-the-game</link><guid isPermaLink="false">693d1c125bc0c2490bd8005e</guid><pubDate>Sat, 13 Dec 2025 07:57:26 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/34570b_41bc68341f1d469eb011716d1dfc627c~mv2.jpg/v1/fit/w_784,h_441,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Samin Nasr-azadani</dc:creator></item><item><title><![CDATA[️ Time Is the Real Map (The Hidden Dimension of Navigation)]]></title><description><![CDATA[Every coordinate, every path, every movement we track begins with time. We talk about position as distance, geometry, or direction, but under every navigation system lies a deeper truth: position is just time, measured precisely enough. When a receiver determines where you are, it’s not really finding “space”. It’s comparing how long each satellite’s signal took to arrive. Trilateration is, in fact, multilateration in time.]]></description><link>https://saminnasrazadani.wixsite.com/saminnasr/post/time-is-the-real-map-the-hidden-dimension-of-navigation</link><guid isPermaLink="false">693d1aa540218b721c725c03</guid><pubDate>Sat, 13 Dec 2025 07:55:17 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/34570b_df5965b603644635b0494bd97a7103b1~mv2.png/v1/fit/w_1000,h_720,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Samin Nasr-azadani</dc:creator></item><item><title><![CDATA[How Location-Based Apps Predict Traffic and Help You Find the Fastest Route]]></title><description><![CDATA[You’ve probably experienced it many times: you follow the suggested route in a navigation app, arrive much faster than expected, and wonder how the app chose a completely different path from what you had in mind.

The received power of a GPS L1 signal at ground level is roughly −130 dBm, meaning the receiver is essentially trying to detect “a signal with nearly zero power” through atmospheric attenuation, ionospheric delay, and system noise. This single fact explains why Jamming and Spoofing can have such profound effects on positioning...]]></description><link>https://saminnasrazadani.wixsite.com/saminnasr/post/gnss-under-attack-a-deeper-technical-insight-into-jamming-spoofing</link><guid isPermaLink="false">6922bd8918f3b71d4fdd0862</guid><pubDate>Sun, 23 Nov 2025 07:54:15 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/34570b_fb331d4de5af4414af5c801aaeaeb74f~mv2.jpg/v1/fit/w_1000,h_720,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Samin Nasr-azadani</dc:creator></item><item><title><![CDATA[ The Layers of Integration (From Sensors to Intelligence)]]></title><description><![CDATA[For decades, integration in navigation meant one thing: blending sensors.
