Software Dependencies
SBG Qinertia
SBG provides the Qinertia Post-Processing Kinematic software for post-processing GNSS and intertial navigation data from the latest GRYFN remote sensing systems integrated with the SBG Quanta Micro. When supplied with the proper configuration files, Qinertia outputs custom GRYFN trajectory and event files used in the GRYFN Processing Tool pipeline.
For tutorials on processing GNSS-Inertial data in Qinertia, please see SBG's support page at https://support.sbg-systems.com/sc/qd/latest/getting-started
Applanix POSPac
GRYFN’s strategic partner for GNSS-Inertial solutions, Applanix™ Corporation, provides Position and Orientation System Post-processing Package (POSPac) which is required to post-process GNSS and inertial navigation data from GRYFN hardware systems integrating an APX-15. When supplied with the proper configuration file, POSPac outputs a custom GRYFN trajectory format which is used in GRYFN’s processing software.
Although GRYFN hardware solutions incorporate Applanix navigation components, processing data from systems using other solutions is possible, provided the format is compatible. An outline of the GRYFN trajectory format is give in this document's Data Bundle Inputs section.

Headwall SpectralView
For GRYFN systems incorporating legacy spectral sensing solutions from Headwall Photonics, raw sensor data is not radiometrically calibrated. Although the empirical line method (ELM) employed in GRYFN processing software provides reflectance calibration for any type of data input (digital numbers or radiance), it is recommended to first convert the raw DNs to radiance values using Headwall’s SpectralView software for Nano HS. For new nHP sensors, the radiance conversion process is implemented natively in GRYFN Processing Tool when the radioCal.raw folder is in the GRAW VNIR data folder in the GRAW (next to settings.txt). For legacy nHS sensors, this process must be performed manually by the user. An outline of this process is provided in the Quick Start Guide.
Headwall BatchProcessingTool
For GRYFN systems incorporating legacy spectral sensing solutions from Headwall Photonics, raw sensor data is not radiometrically calibrated. Although the empirical line method (ELM) employed in GRYFN processing software provides reflectance calibration for any type of data input (digital numbers or radiance), it is recommended to first convert the raw DNs to radiance values using Headwall’s BatchProcessTool for SWIR640. For legacy uVS sensors, this process must be performed manually by the user. An outline of this process is provided in the Quick Start Guide.
