GNSS Positioning Solutions Introduction Rakon is the world leader in providing innovative oscillator technology for GNSS applications. The need for extreme precision under challenging conditions and accurate location in emergency situations, is driving the demand for high performance TCXOs. Rakon has developed a portfolio of cost effective solutions which meet these performance requirements. Rakon’s TCXOs for GNSS offer less than 0.5 ppm stability, low g sensitivity, tilt compensation and best in class phase noise performance. With a wide range of frequency control products for many GNSS applications, Rakon’s products have set the standard for consumer global GNSS applications. Rakon is the preferred supplier of frequency control products for GNSS. Technology Expertise and Standards Compliant Rakon TCXOs Enable the Highest Level of Performance for GNSS Rakon pioneered the ±0.5ppm TCXO which became the world’s timing reference standard for global positioning systems. Rakon has further advanced TCXO technology for GNSS, enabling reliable locking conditions – even under weak signal environments. This coupled with Rakon’s unmatched engineering expertise in the design and manufacture of low phase noise, tilt-compensation to guarantee performance for life of equipment, low ageing, extended temperature from -55°C to 105°C, high stability TCXOs, leads the way for GNSS solutions requiring the highest level of performance. Proprietary Testing Technology COSPAS-SARSAT Standards Compliant Testing is critical in the frequency control product industry. The electro-mechanical nature of quartz means it’s impossible to eliminate all anomalies and products must be fully tested and screened. Rakon designs and manufactures its own crystal and TCXO test and process equipment. The guaranteed temperature sensitivity and advanced testing to eliminate spurious frequencies (caused by activity dips) reduces signal lock issues and ensures enhanced GNSS experience Rakon’s high resolution testing is unique in the industry, screening out all frequency perturbations. The RFPT100 is the only COSPAS-SARSAT compliant TCXO available. It incorporates Rakon’s Pluto™ ASIC which is a fourth-order temperature-compensation chip. The Pluto™ ASIC uses certain patented features, enabling it to achieve the critical medium term stability required, and which was previously unattainable with any TCXO. This unique performance for the first time has enabled the use of compact, low-cost TCXOs in emergency beacon applications. The Pluto™ ASIC based TCXO employs One-Time Programmable (OTP) non-volatile memory which ensures lifetime reliability under adverse conditions. Low g-Sensitivity Rakon’s low g sensitivity TCXO uses its proprietary Pluto+™ ASIC, and a patented dual crystal resonator design, resulting in high frequency stability over a wide temperature range, paired with a better than 0.2 ppb/g acceleration sensitivity.
