1. Solar Probe Plus FIELDS MEP iPSR SOC Marc Pulupa April 10, 2017

2. SPP FIELDS SOC Overview
The FIELDS SOC allows the FIELDS SOC team and Science teams to:
Efficiently command and control the FIELDS instrument, both during ground testing and on-orbit operations.
Process and distribute FIELDS science data in a timely, accurate, and configuration-controlled fashion.
Solar Probe Plus is an encounter-based mission:
Command sequences will be optimized for each encounter and uploaded via the FIELDS SOC.
Solar Probe Plus opportunities for telemetry downlink and command uplink are limited:
For the FIELDS instrument suite, these resources will be managed through the FIELDS SOC.

4. FIELDS SOC S/C Level Testing
GSEOS provides APID binary files and data to Tmlib server
Some subsystems use APID files to validate data, others use Tmlib
Configuration similar to FIELDS TVAC

5. FIELDS MOC-SOC Activities
MOC-SOC connectivity test
Test successfully performed w/FIELDS SOC at UCB 17 Jan 2017
Test successfully performed w/local FIELDS SOC at APL 22 Feb 2017
ISCF file delivered
Received real-time telemetry from the MOC
FIELDS SOC provided inputs to MOC/MOPS teams for support of upcoming activities
Packet filter table: first ‘notional’ version provided, will provide final ‘commissioning’ version for MSIM2 before 14 Apr 2017
Real-time APID table: will provide before 14 Apr 2017
SPP Instrument Critical HK packet information
Science planning inputs and feedback for Dry Run activity
FIELDS personnel need NACI clearances

9. FIELDS SOC Development Schedule
FIELDS SOC schedule will fulfill requirements prior to MSIM 3 (Jan 2017).
FIELDS SOC makes use of already developed IDL software (SPEDAS/TDAS for display/analysis, MMS SITL tool for burst selection, IDL analysis routines from FIELDS subsystems)
Applying calibrations which have been provided to the SOC from FIELDS subsystems
Development effort consists largely of adapting existing analysis routines to produce data in a format compatible with Science Data Management Plan
Details on outstanding requirements contained in following slides

10. SOC 02-03: FIELDS Calibration Coefficients
Subsystem
Calibration Data Status
AEB
Specified in FIELDS1 CTM
DCB
DFB
Calibration data and plots provided to SOC
MAG
Calibration data provided in MAG test report
Preamplifiers
Board level calibration data on FIELDS SVN site
RFS
Calibration data and plots on FIELDS SVN site
SCM
Calibrations to be delivered with FM SCM (same format as those delivered for EM)
TDS
Board level gain/phase curves measured in bench testing at UMN

11. SOC-04: Burst data
FIELDS (and SWEAP) SOC will adapt MMS EVA burst data display and selection tool

12. SOC-07: Quicklook Data
FIELDS SOC will provide quicklook plots on the FIELDS webpage
fields.ssl.berkeley.edu
Quicklook plots made from L1-L2 data
Low latency, used for burst data selection
Example summary quick look plot using THEMIS data
themis.ssl.berkeley.edu/summary

13. SOC-09: Delivering data to NASA
FIELDS will make L2+ data publicly available in ISTP-compliant CDF files in a directory on the SSL data server
sprg.ssl.berkeley.edu/data
Similar to THEMIS, MAVEN, STEREO, RBSP, Wind
L1 data (engineering units) will be available in a separate directory on the same server, with access granted to other SPP teams
All levels of data will be regularly backed up using standard SSL IT procedures

14. SOC-10: Displaying Shared Data Telemetry
FIELDS SOC is an active participant in shared science planning activities. These include the regularly scheduled SOC telecons as well as:
MOC-SOC connectivity tests
Science Planning Tool Requirements Review
Orbit Planning Dry Run
FIELDS SOC will use graphical and machine readable output of Science Planning tool to predict available telemetry, and participate in SWG/shared planning activities to determine telemetry allocations per orbit
FIELDS SOC will monitor and display downlinked telemetry

15. SOC-11: Science Data Management Plan
Making publicly accessible ISTP-compliant CDF files is the primary FIELDS activity for demonstrating FIELDS compliance with SDMP
As with SOC-09 requirement, implementation will be similar to previous UCB/SSL missions such as THEMIS, MAVEN, STEREO, RBSP, Wind

16. SOC-14 to SOC-21: Display and Analysis of Data
FIELDS SOC produced CDF files (see response to SOC-09) will be able to be plotted and analyzed using IDL-based analysis software (SPEDAS/TDAS) developed at UCB
