🛰️ October 23 isn’t just another day. Every October 23 (10.23), we celebrate something far deeper, the invisible rhythm that keeps our world in sync. 🌍 This number enables: 📶 Telecom networks and 5G synchronization 🏦 High-frequency financial trading timestamps ⚡ Grid stability and power-system timing 🛡️ Defence mission operations 🚁 Autonomous drones, precision agriculture & aviation safety 🚀 Celebrating International GNSS Day (Courtsey: The Institute of Navigation), 10.23 MHz, the frequency that changed the world. 🛰️ Every now and then, we hear about the L-band used in Navigation, specifically L1, L2, and L5: • L1 = 1575.42 MHz • L2 = 1227.60 MHz • L5 = 1176.45 MHz Now, have you notice something common in these numbers? 🤔 Divide them by today’s date 10.23: • L1 = 1575.42 / 10.23 = 154 • L2 = 1227.60 / 10.23 = 120 • L5 = 1176.45 / 10.23 = 115 ✨ Isn’t that fascinating! Not just this, the PRN code length, the chipping rate all are governed by this number. 🧭 The entire architecture of the Global Navigation Satellite System (GNSS): #NavIC, #GPS, #Galileo, #GLONASS, #BeiDou, and #QZSS traces back to one fundamental frequency: 10.23 MHz. Chosen by the GPS design team in the 1970s, this wasn’t random, it’s the master clock frequency from which every pseudorange code, carrier phase, and precise timing pulse is derived. 💡 Why exactly 10.23? (This deserves a separate post, a 50-year-old engineering choice/constraint that still drives the entire world’s timing.) It’s one of humanity’s quietest yet most transformative number. As we celebrate #InternationalGNSSDay, it’s a reminder to our GNSS & PNT community of a shared mission: 🚀 To make navigation and timing more accurate, reliable, and resilient for billions who depend on it, often without realizing it. 🌐So today, on 10/23, let’s appreciate the #engineers, #physicists, and #space_technologists who made “location & timing” a universal utility. At VyomIC, we understand how critical every decision can be, it has the power to shape the next 50–100 years. So why not be a little more sophisticated? #InternationalGNSSDay #GNSS #PNT #NavIC #GPS #Timing #Innovation #LEOPNT #VyomIC Vibhor Jain Anurag Patil #PNT means VyomIC.

🌍 Happy International GNSS Day 🛰️! Today we celebrate the power of global navigation satellite systems: positioning, navigation & timing (PNT) technologies that quietly shape so much of modern life. A huge thank you to The Institute of Navigation (ION) for this great resource to mark the day: https://lnkd.in/dp4463mr 📍 The date Oct 23 (10.23) honours the GPS foundational frequency 10,23 MHz, the ”heartbeat” of GNSS 📍This year marks 30 years of the Galileo programme and a milestone for GNSS innovation 📍From transport and agriculture to surveying, aviation & so much more beyond, GNSS enables accurate location and time Cheers to GNSS 🎉!

ESA Navigation is celebrating International GNSS Day this year with a photo expo highlighting important moments in the history of European satellite navigation—in ESA's technical heart in Noordwijk, the Netherlands.

Happy International GNSS Day and greetings from our HQ in Toulouse with our team & partners! 🛰️ Initiated by The Institute of Navigation, International GNSS Day is an opportunity to recognize and celebrate the technologies, innovations, and people shaping Global Navigation Satellite Systems. This year’s edition was particularly special, marking the 30th anniversary of Galileo, the European Union’s own GNSS constellation. 🌍 Developed by the European Union through the European Space Agency - ESA, Galileo provides highly accurate positioning and timing services that strengthen the EU’s autonomy and innovation in navigation. To honor this milestone, we organized a friendly event at our offices with our employees and partners, including a Galileo-themed quiz to learn more about this remarkable program while sharing a great moment together. A big thank you to the ION for launching this inspiring initiative, and to everyone who joined us in celebrating the power and future of GNSS! 💫

Today's date, 10.23, mirrors the foundational GPS frequency of 10.23 MHz, the original heartbeat of GPS satellites, signals, and receivers. That's why The Institute of Navigation (ION) has declared October 23 "International GNSS Day," recognizing the vital role that Global Navigation Satellite Systems (GNSS) play in keeping our modern world running. To honor the occasion, take a moment to ask yourself: "What trusty navigation systems are unwittingly leading me—or my team—astray?" And to help answer that question, check out Episode 107 of 𝘛𝘩𝘦 𝘌𝘯𝘦𝘳𝘨𝘺 𝘋𝘦𝘵𝘰𝘹, which applies the 𝐏𝐨𝐬𝐢𝐭𝐢𝐨𝐧𝐢𝐧𝐠, 𝐍𝐚𝐯𝐢𝐠𝐚𝐭𝐢𝐨𝐧, 𝐚𝐧𝐝 𝐓𝐢𝐦𝐢𝐧𝐠 (𝐏𝐍𝐓) principles behind GPS technology to help you steer yourself—and others—in the right direction.
