Rakon發布適用于低軌衛星星座的小型GNSS接收器
Rakon releases small form factor GNSS Receiver for LEO satellite constellations
Rakon is proud to introduce its new GNSS Receiver DB (Daughter Board), the first product in its suite of next generation equipment for NewSpace missions. The GNSS Receiver DB is a compact off-the-shelf GNSS Receiver with low power consumption and is specifically designed for small and nanosatellites. With multi-band and multi-constellation support, the equipment can process signals from up to 448 channels simultaneously to provide high performance position, velocity and timing.
The GNSS Receiver DB supports NewSpace satellites and nanosatellites across most GNSS satellite constellations. Supported GNSS and Radio Frequency (RF) signal bands, important for modern navigation purposes worldwide, are listed below:
This miniature equipment can be used on its own, but can also be easily combined into larger-sized motherboards, such as Rakon’s PC104 PCB. Moreover, it can be adapted into other space platform equipment to meet specific requirements.
The GNSS Receiver DB’s mono-antenna can be set to active or passive. An active antenna enables the GNSS Receiver to reject unwanted radio frequencies (RF) and lower the signal-to-noise ratio (SNR) using low noise amplifiers (LNAs) close to the antenna. It provides high transmit power and better impedance match to the antenna.
Key Specifications:
Support 448 multi-constellation, multi-band channels
Time To First Fix (TTFF): Warm start < 20s, Cold start < 45s
Position accuracy < 1.2 m (800 km altitude)
Precise 1PPS signal output
Low power consumption: 0.6 to 1.1W
Low supply voltage: 3.3 V
The GNSS Receiver DB is part of a larger range of frequency control and timing synchronisation products for NewSpace missions, consisting of NewSpace Equipment as well as Phase Lock Oscillators, Ultra-Stable Oscillators, Low Power & Low Phase Noise Oscillators and Clock Drivers. Our products operate on platforms and payloads supporting Telecommunications, Earth Observation (EO), Scientific Research, LEO PNT (Position, Navigation and Timing) and SBAS (Space Based Augmentation Systems).
Rakon發布適用于低軌衛星星座的小型GNSS接收器
Rakon瑞康晶振公司自豪地推出其新的GNSS接收器數據庫(子板),這是其用于新空間任務的下一代設備套件中的第一款產品。GNSS接收機DB是一種低功耗的緊湊型現成GNSS接收機,專門為小型和超小型衛星設計。憑借多頻段和多星座支持,該設備可以同時處理多達448個通道的信號,以提供高性能的位置、速度和時序。
全球導航衛星系統接收器數據庫支持跨越大多數全球導航衛星系統衛星星座的新空間衛星和納米衛星。以下列出了對全球現代導航目的非常重要的支持GNSS和射頻(RF)信號波段:
這種微型設備可以單獨使用,但也可以很容易地組合成更大尺寸的主板,如Rakon的PC104 PCB。此外,它可以適應其他空間平臺設備,以滿足特定的要求。
GNSS接收機DB的單天線可以設置為有源或無源。有源晶振,有源天線使GNSS接收機能夠利用靠近天線的低噪聲放大器(lna)抑制不需要的射頻(RF)并降低信噪比(SNR)。它提供高發射功率和與天線更好的阻抗匹配。
主要規格:
支持448個多星座、多頻段頻道
首次修復時間(TTFF):熱啟動< 20秒,冷啟動< 45秒
位置精度< 1.2米(800公里高度)
精密1PPS信號輸出
低功耗:0.6至1.1W
低電源電壓:3.3V
GNSS接收機DB是用于新空間任務的更大范圍的頻率控制和定時同步產品的一部分,包括新空間設備以及鎖相振蕩器、超穩定振蕩器、低功率和低相位噪聲振蕩器和時鐘驅動器。我們的產品在支持電信、地球觀測(EO)、科學研究、低地球軌道PNT(定位、導航和定時)和SBAS(天基增強系統)的平臺和有效載荷上運行。
GNSS接收器DB是作為子板(DB)格式提出的高度集成的NewSpace GNSS接收器。這是一個現成的全球導航衛星系統,石英晶體振蕩器,低功耗接收器,專為小型和納米衛星設計。該先進的解決方案支持多頻段和多星座,使子板GNSS接收器能夠同時處理多達448個信道的信號,以提供高性能的位置、速度和定時。
與Rakon的先驅NewSpace GNSS接收器相比,GNSS接收器DB的占地面積不到PC1041卡的一半。它可以很容易地集成到主板或直接集成到太空設備中。新一代全球導航衛星系統接收器支持無源和有源天線。
全球導航衛星系統接收器數據庫是Rakon新太空設備組合的一部分,該組合包括用于新太空任務的定時和頻率分配產品(MRO)、全球導航衛星衛星系統接收器和s波段通信設備。
Rakon石英貼片晶振頻率控制產品和定時解決方案支持5G網絡的閃電般速度、自動駕駛汽車的精確定位、云計算的同步等等。我們的產品甚至到達了火星。了解更多關于我們公司和產品的信息,這些產品是當今通信和定位技術的核心。
