Automatic Multi-Constellation, Multi-Frequency
When using TerraStar service, a multi-constellation, multi-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 TerraStar subscription, a multi-constellation, multi-frequency configuration
is automatically activated included with TerraStar-X, TerraStar-C PRO or RTK ASSIST PRO subscriptions.
To enable multi-constellation, multi-frequency channel configurations while a TerraStar-X, TerraStar-C PRO or
RTK ASSIST PRO subscription is active, a receiver reset is required.
TERRASTARCHANCONFIG ENABLE
SAVECONFIG command
For more information, or to disable Multi-Constellation, Multi-Frequency channel configuration, see the
TERRASTARAUTOCHANCONFIG
command.
If the TerraStar-X, TerraStar-C PRO or RTK ASSIST PRO subscription becomes inactive, the receiver
will revert to the channel configuration enabled by the receiver model.
This feature is available on OEM firmware version 7.06.01 and later.
3.9 RTK ASSIST
RTK ASSIST™ is a feature that enables centimeter-level accuracies to be maintained through extended RTK
correction outages. With RTK ASSIST, RTK-dependent operations can continue through RTK correction out-
ages as long as 20 minutes.
RTK ASSIST uses correction data provided by TerraStar. To obtain these corrections, an L-Band capable
receiver is required and L-Band tracking must be enabled using the
ASSIGNLBANDBEAM
command.
RTK ASSIST also requires a subscription to the RTK ASSIST service. To obtain a subscription, contact your
local NovAtel sales representative or visit
www.novatel.com/products/terrastar-gnss-corrections/
. The NovAtel
Product Serial Number (PSN) is needed to obtain a subscription. The PSN is available from the
VERSION
log.
RTK ASSIST is available as soon as the rover receiver has at least one valid RTK solution and has received the
RTK ASSIST correction data. If an RTK correction outage occurs, then RTK ASSIST will maintain RTK mode
until the subscription-permitted RTK ASSIST duration is exceeded. A shorter, user-defined RTK ASSIST time
out can also be set using the
RTKASSISTTIMEOUT
command. Normal RTK operation will seamlessly resume
if RTK corrections are restored at any point while RTK ASSIST is operating.
