B NEO-D9S L-band configurations
Correction services from several providers are available via the L-band communication satellites. The
service provider will have several correction service specific configurations that need to be configured
before the receiver can provide the relevant service provider data such as:
• Service provider service ID
• Service provider frequency based on geographical location
• Service provider data rate
This means that the frequency allocation for a particular service provider could change. Service
providers do provide information on any frequency changes when required.
The NEO-D9S default L-band configuration keys are listed below:
• CFG-PMP-CENTER_FREQUENCY = 1539812500 Hz
• CFG-PMP-SEARCH_WINDOW = 2200 Hz
• CFG-PMP-USE_SERVICE_ID = 1 (true)
• CFG-PMP-SERVICE_ID = 50821
• CFG-PMP-DATA_RATE = 2400 (B2400) bps
• CFG-PMP-USE_DESCRAMBLER = 1 (true)
• CFG-PMP-DESCRAMBLER_INIT = 23560
• CFG-PMP-USE_PRESCRAMBLING = 0 (false)
• CFG-PMP-UNIQUE_WORD = 16238547128276412563
The NEO-D9S correction data receiver is fully compliant with the u-blox configuration concept. The
messages UBX-CFG-VALSET, UBX-CFG-VALGET and UBX-CFG-VALDEL are used to configure the
above keys. See the NEO-D9S Integration manual [1] for further details.
