Oceanix Correction Services

To use Oceanix Correction Services and obtain a PPP solution, perform the following steps.

  1. Ensure the GNSS system has the required components. See Required Hardware.

  2. Ensure the OEM7 receiver has a model that supports Oceanix Correction Services. See Receiver Models Needed for Oceanix Correction Services.

  3. Enable L-Band tracking on the receiver. See Enable L-Band Tracking.

  4. Obtain a subscription to Oceanix Correction Services. See Oceanix Subscriptions.

Required Hardware

The GNSS system requires the following components:

  • An OEM7 receiver
    (OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7 or CPT7700)

  • A GNSS antenna capable of receiving L-Band signals.

    For the best Oceanix performance, select a GNSS antenna that provides full GNSS signal support. (i.e., GPS L1/L2/L5, GLONAS L1/L2, Galileo E1/E5a/E5b/E6 and BeiDou B1C/B2a/B2b/B3)

    Refer to our web site novatel.com/products/gps-gnss-antennas for information about NovAtel L-Band-capable antennas.

  • Receiver firmware that is compatible with Oceanix Correction Services.

    • OEM7 receivers – firmware version 7.05.00 or later

    Firmware version 7.08.14 or later is required for the best convergence performance.

    For instructions on upgrading the OEM7 receiver firmware, see NovAtel Firmware.

Receiver Models Needed for Oceanix Correction Services

Specific receiver models are required to use the correction data provided by Oceanix Correction Services.

To check the model of the receiver:

  1. Request the VERSION log to view the current receiver model.

    log version once

  2. Compare the model number of the receiver to the model required for an Oceanix subscription. The first four letters of the receiver model must match the letters in the table below.
    In the example above, the OEM7 receiver model number is FFNRNNCBES1.

     

     

    Oceanix

    OEM719, OEM729, OEM7700, PwrPak7, CPT7700

    Minimum model required

    DDN-P​

    Model for full functionality

    FFN-P

    OEM7500, OEM7600, OEM7720, PwrPak7D, CPT7

    Minimum model required

    DDN-P

    Model for full functionality

    MFN-P

    Notes about the fourth letter. A P model (e.g. DDN-P) meets the requirements for L and P. An R model (e.g. FFN-R) meets the requirements for L, P and R.

    Models that enable Oceanix also enable the Subscription Managed Channel Configuration feature. For more information, see Subscription Managed Channel Configuration.

  3. If the receiver does not have the minimum model required, or if you want to upgrade to full Oceanix functionality, contact your local NovAtel sales representative to upgrade the receiver model.

Enable L-Band Tracking

The receiver must be powered and tracking the L-Band signal from an Oceanix satellite prior to the planned activation time.

Send the ASSIGNLBANDBEAM command to configure the receiver to track the Oceanix satellite.

ASSIGNLBANDBEAM auto

To confirm the receiver is tracking of an L-Band signal, request the LBANDTRACKSTAT log to view the L-Band tracking status information.

log lbandtrackstat

If the receiver is tracking an L-Band signal from an Oceanix satellite, the tracking status word (shown in bold in the example above) of the LBANDTRACKSTAT log will be 00c2. In the example above, the tracking status word indicates that the receiver has locked onto the signal from "98W" and "AORW", but not "POR".

The latest services and coverage can be obtained from novatel.com/products/gps-gnss-correction-services/oceanix-correction-services. For additional information on Oceanix activation, contact NovAtel Customer Service at novatel.com/support.

Oceanix Subscriptions

A subscription is required to use Oceanix Correction Services for near shore applications. Near shore applications are defined as vessels operating within 10 km of shore.

For more information about Oceanix services, visit novatel.com/products/gps-gnss-correction-services/oceanix-correction-services.

Obtain a Subscription

To obtain a subscription, contact your local NovAtel sales representative.

The NovAtel product serial number (PSN) is needed to obtain a subscription. Request the VERSION log to view the receiver serial number.

In the example above, the receiver serial number is BMHR17090005E.

Verify the Subscription Status

After a subscription is purchased, the subscription activation signal can be broadcast at the time of the service activation (default), or at a specified start date and time (upon user request).

The receiver must be configured to track the Oceanix signal prior to the subscription start time. See Enable L-Band Tracking.

To confirm the Oceanix subscription status, request the OCEANIXSTATUS log:

log oceanixstatus

<OCEANIXSTATUS USB1 0 51.5 FINESTEERING 2232 495334.510 02000020 049a 16809
<     ENABLE LOCKED IN_REGION

The first field will be ENABLE to indicate the Oceanix subscription is valid. The second field will be LOCKED to indicate the decoder is locked to the data format.

Monitor PPP Convergence

The PPP position calculated using Oceanix Correction Services is not ready for use until the PPP solution has converged.

To monitor the PPP convergence, request the PPPPOS log:

log ppppos ontime 1

<PPPPOS USB1 0 47.5 FINESTEERING 2232 424797.000 02000020 9078 16809
<     SOL_COMPUTED PPP_CONVERGING 51.15043905734 -114.03067597608 1096.6201 -17.0001 WGS84 0.6791 0.4277 1.7640 "TSTR" 17.000 0.000 34 34 34 33 00 00 7f 37

Initially the position type will report PPP_CONVERGING. After the PPP solution has converged, the position type will change to PPP.

Subscription Managed Channel Configuration

When using Oceanix service, an all constellation, all frequency channel configuration gives better accuracy and faster convergence time compared to a dual-constellation, dual-frequency channel configuration. To allow the receiver to make best use of the Oceanix subscription, the Subscription Managed Channel Configuration (SMCC) feature automatically changes the channel configuration of the receiver to ensure all available constellations and frequencies are used. The specific channel configuration used is shown in the table below.

Receiver

Oceanix

OEM719, OEM729, OEM7700, PwrPak7, CPT7700

FF config (7)

OEM7500, OEM7600, PwrPak7D, CPT7

MF config (6)

For information about channel configurations, refer to the SELECTCHANCONFIG command and the CHANCONFIGLIST log.

SMCC is enabled by default. To disable SMCC, issue the following commands:

TERRASTARAUTOCHANCONFIG DISABLE

SAVECONFIG

To enable SMCC, issue the following commands:

TERRASTARAUTOCHANCONFIG ENABLE

SAVECONFIG

If an Oceanix subscription is active, a receiver reset is required after issuing these commands.

For more information, see the TERRASTARAUTOCHANCONFIG command.

The automatically applied channel configuration takes effect on the next receiver restart after the Oceanix subscription is received.

If the Oceanix subscription becomes inactive, the receiver will revert to the channel configuration enabled by the receiver model.

This feature is available on OEM firmware version 7.08.10 and later.
