The C-Nav Subscription Service, now called C-NavC
1
, remains unaffected and continues to
provide customers with full GPS clock and orbit correctors. C-NavC
1
has proven reliability since
2000, featuring JPL/NASA clock and orbit based C-Nav proprietary correction algorithms, a
global network of dual frequency reference sites, fully independent servers in geographically
separated processing centers and simultaneous broadcasts from two independent satellite
networks (Net-1 and Net-2) to ensure a reliable worldwide positioning solution.
The C-Nav3050 receiver combined with the C-NavC
2
subscription service delivers PPP
correctors for all operational GNSS satellites, showing significantly enhanced performance in
shaded conditions and increased position accuracy. There is up to 20 percent reduction in PPP
start-up pull-in time accuracy, now with two completely independent solutions available (C-
NavC
1
and C-NavC
2
). There are no additional fees for access to the new C-NavC
2
correction
service, giving users the best of both worlds.
How to Access the C-Nav Subscription Service
C-Nav is a subscription service. The user pays a subscription, which licenses the use of the
service for a predetermined period of time.
Subscriptions can be purchased for any predetermined period of time and are available via a C-
Nav authorized representative, or by contacting C-Nav at:
An authorized subscription will provide an encrypted key, which is specific to the Serial Number
of the C-Nav receiver to be authorized. This is entered into the receiver using a C-Nav controller
solution such as the C-NaviGator II CDU, C-Monitor or C-Setup PC software, or Over the Air (C-
Nav3050 only).
When contacting C-Nav regarding subscription or deactivation of service, please have the
following information available:
Company Name and Contact Information
PO/Reference No.
Vessel Name, Location and No. (if applicable)
Required Start/Stop Date or Period
Service Type (Land or Offshore/Activation or Deactivation)
Operational Region
Receiver Type
The only piece of equipment needed to access the C-Nav system is a C-Nav receiver. C-Nav
offers a variety of receivers configured for different applications. Details of all the C-Nav
receivers are available from a C-Nav authorized local representative or on the C-Nav website at:
