BPS is a GPS alternative working over ATSC 3.0 digital TV signals

Broadcast Positioning System (BPS) is an alternative to GPS designed for timing and positioning over ATSC 3.0 digital TV signals, and mainly designed as a backup solution for national security. GPS is critical in providing not only location data, but also timing data for critical infrastructure such as power grid, telecommunication networks, and so on. However, GPS signals can be spoofed, and/or satellites could potentially be damaged or even taken down. That’s where BPS comes in as an alternative with a much broader network of base stations, and both GPS and BPS signals can be compared, meaning it can be used to detect spoofing as well. It works by adding a preamble with timing data and a Data PLP (Physical Layer Pipe) with tower information and location. One tower is enough for timing data, and positioning will also be possible with four towers within range. Time accuracy is 100ns (95% […]

Radxa Dual 2.5G Router HAT adds 2.5GbE networking and M.2 NVMe storage support to Raspberry Pi 5-compatible SBCs

The Radxa Dual 2.5G Router HAT is an expansion board adding 2.5GbE networking and an M.2 PCIe x1 socket for NVMe SSD storage to the Raspberry Pi 5 and compatible SBCs with a PCIe FFC connector. We had previously seen Raspberry Pi 5 HATs with 2.5GbE such as the Pineberry HatNET! 2.5G, or even one with 2.5GbE and NVMe SSD (52Pi W01 U2500 HAT), but the Radxa Dual 2.5G Router HAT is the first to implement two 2.5 Gbps Ethernet ports to enable routing, and also features an NVMe SSD as a bonus. Radxa Dual 2.5G Router HAT specifications: Supported SBCs – Raspberry Pi 5, Radxa ROCK 2F, Radxa ROCK 2A, Radxa ROCK 5C, the upcoming Radxa 4D (RK3576), and potentially others PCIe Switch – ASM2806 PCIe 3.0 switch chip with PCIe Gen3 x2 upstream and four PCIe 3.1 lanes downstream up to 8GT/s Storage – 1x M.2 M-Key socket […]

Mono Gateway – A 10GbE nano-ITX router board powered by NXP Layerscape LS1046A

Mono Gateway 10GbE Nano ITX router board

The Mono Gateway is a nano-ITX router board powered by an NXP LayerScape LS1046A quad-core processor and equipped with two 10GbE SFP+ cages, three gigabit Ethernet RJ45 ports, and M.2 sockets for wireless WiFi 6 and/or tri-band WiFi 5, Bluetooth, and Thread modules. Tomaž Zaman’s YouTube channel description reads “I hate routers”, and that’s exactly why the “Gateway” came to life. He wanted a router that meets his expectations and runs open-source software. The NXP Layerscape LS1046A was selected thanks to its ability to support 10 Gbps Ethernet with up to 26 Gbps line-rate throughput for VLANs, PPPoE, and NAT. Let’s have a look. Mono Gateway specifications: SoC – NXP Layerscape LS1046A quad-core Cortex-A72 processor @ 1.6 GHz System Memory – 8 GB ECC RAM @ 2100 MT/s Storage 32 GB eMMC flash for the OS 64 MB NOR flash for the bootloader Networking 2x SFP+ 10 Gbps Ethernet cages […]
