C-Nav introduces next generation high-performance GNSS receiver

The latest addition to the C-Nav range of precise positioning solutions is now available. Delivering unprecedented accuracy, the C-Nav3050 GNSS receiver has been specifically designed to meet the changing needs of users. A simple upgrading path allows customers to tailor the C-Nav3050 from a single frequency receiver to a powerful geodetic quality instrument - all in the same hardware.

C-Nav3050 is powered by the new 66 GNSS channel Sapphire circuit board making the receiver uniquely suited for real-time applications including precise positioning, offshore surveys and engineering, DP input, hydrography (exceeds highest IHO standards), coastal and military applications, marine airborne reconnaissance and survey.


Superior interference suppression (both in-band & out-band), multipath mitigation, and measurement accuracy are only a few of the sensor's technological advances. The Sapphire GNSS engine incorporates several patented innovations, delivering near optimal GPS P-code recovery with a significant signal-to-noise ratio advantage over competing technologies.

Performance upgrade path

The C-Nav3050 performance upgrade path allows users to adapt to changing requirements via simple software upgrades avoiding the need to purchase costly additional hardware. The C-Nav3050 software-enabled features, bundled or purchased individually, cover the widest variety of GNSS applications.

C-Nav3050 GNSS receiver

The C-Nav3050 comes fully functional with a demodulator inbuilt to receive the C-Nav real-time RTG correction service; a single set of Precise Point Positioning corrections providing decimeter level accuracy across the globe, 24/7.Positioning flexibility

GNSS data sampling options include GPS (L1, L2, L2C, L5); GLONASS (G1, G2); Galileo (E1, E5a).

The C-Nav3050 also accepts WAAS, EGNOS, MSAS, GAGAN (RTCA/DO-229D compliant) code corrections via two internal Satellite Based Augmentation System (SBAS) channels with auto-configuration to use the most suitable correction source available.

Raw measurement data and Position, Velocity, & Time are provided at 5Hz in the standard configuration with optional upgrades to 10, 25, 50, and 100Hz via high speed ports.

C-Nav RTK/UltraRTK

The patented RTK/UltraRTK algorithm provides fast initialization and the ultra-compact binary format ensures robust data performance at all times. The C-Nav3050 is capable of outputting or accepting legacy 0x5B (RTK) or 0x5E (UltraRTK) binary formats.

RTK Extend

The unique RTK Extend feature allows continuous real-RTK/RTK level positioning accuracy during radio communication interruptions by utilizing the C-Nav global correction service. By overcoming the drawbacks of traditional RTK, the C-Nav3050 with RTK Extend maintains centimeter level positioning during communication loss for up to 15 minutes.

Performance

The C-Nav3050's Sapphire GNSS engine delivers more than 50% signal-to-noise ratio advantage over competing technologies. This results in improved real time positioning in the most challenging of multipath environments.

Rugged design

The C-Nav3050 conforms to MIL-STD-810F for low pressure, solar radiation, rain, humidity, salt-fog, sand, and dust. The unit is also IP certified to the IP67 level and complies with type approval procedures of the Marine Equipment

شكرا يامحمد على المعلومات المفيده عن هذا الجهاز

واكثر الاشياء المفيده فى هذا الجهاز بالنسبه لعملى هى RTK Extend فعاده مانفقد الاتصال مع المحطه الارضيه مرتين يوميا او اكثر لمده تتراوح بين 10-15دقائق.
معنى هذا انه عند استخدام هذا الجهاز فاننا لن نفقد التصحيح خلال اليوم كله وهذا من الاشياء الهامه جدا فى اعمال التكريك

حيث ان الكراكات تعمل على نظام RTK بدقه عاليه

اما اذا فقدنا التصحيح من المحطه الارضيه فان الحفر لن يكون دقيقا خاصه اذا كانت الكراكه تقوم بالعمل على الميول او على جوانب الممر الملاحى
وسنضطر الى العمل على قراءات جهاز المد والجزر والذى عاده مايوجد فى الميناء ومن الممكن ان يبعد حوالى 15 كم عن منطقه العمل مما يعنى ان هناك اختلاف بين قيمه المد والجزر بين منطقه العمل والمنطقه التى بها جهاز المد والجزر
