J-Field 4.0.1.663 has been released, featuring NTRIP Caster setup for compatible JAVAD Bases and improved UHF detection and RAMS connectivity.
Release 4.0.1.663
- Thread starter Armen Harutyunyan
- Start date
Thanks for the continued work on J-Field. I appreciate that rams.javad.com:8800 was hardcoded as the default server for RAMS in J-Field.

Armen,
This is wonderful. I am assuming the NTRIP caster can operate WITHOUT a static IP? Is that correct?
No, this release does not touch any JERCI-related parts, so if you already have JERCI installed, it will remain unchanged.
Yes, the NTRIP caster can technically operate without a static IP. The caster retrieves the current IP address from the Base Station, allowing you to always know the new IP and update the configuration on the client's side. However, for full support of non-static IPs, Dynamic DNS (DDNS) is typically used to automatically resolve the changing address, but please note that DDNS is not yet supported in the current implementation.

Great. Thank you for the info. This definitely provides more flexibility.
Armen, so I am clear on how this works, Javad is hosting a server with the caster for the NTRIP service?
I took a look at this today. It creates a caster hosted on the base station. To not need a static IP with a cellular connection the base needs to connect to a NTRIP server like http://rtk2go.com/
Cellular networks utilize Network Address Translation (NAT). NAT is a technique used to allow devices on a private network to communicate with the Internet. NAT allows devices on a private network to use private IP addresses, which are not globally unique and are not reachable over the Internet, while still being able to communicate with devices on the Internet.

It is still only possible to configure the base to RTK2go through Netview.

With a Triumph-3 'base', that has been enabled with the OAF NTRIP-Caster option.
Then the T-3 'base' can be configured to provide NTRIP 'mountpoints' that can be used by any 'rover' via an Internet connection.
Example of the 'base' NTRIP 'mountpoints' are:
Note: The five available mount points from the source table provide the following types of corrections (in the example, the External Base is TRIUMPH3-00382):
o EXTERNAL_BASE_NAME_A: The corrections on A are configurable via JFIELD 'Remote Base' setup . . .
o EXTERNAL_BASE_NAME_B: RTK RTCM3 MSM GPS+GLO+BDS+GAL
o EXTERNAL_BASE_NAME_C: RTK RTCM3 3.0
o EXTERNAL_BASE_NAME_D: DGPS RTCM
o EXTERNAL_BASE_NAME_E: RTK CMR

Matt,
So based on what your saying, we still need the static IP if we aren't going through a third party hosting service?
Nonetheless, NTRIP caster affords the ability to connect other brands of receivers to JAVAD products and UAV as well. Definitely and upgrade.
Yes, if you are using cellular corrections.

That would be great to have.

Matt,
I have just updated our LS and realized that the NTRIP caster is an additional OAF feature. Can you tell me how much this feature costs?

The NTRIP caster option is $1,000. I believe the NTRIP Server feature (needed for RTK2Go or other NTRIP servers) is included standard with receivers.
