SatLoc Integration Implementation Summary

This document provides a comprehensive overview of the SatLoc API integration implementation based on the actual SatLoc technical documentation.

Overview

The integration allows AgMission to:

1. Upload job data to SatLoc using the UploadJobData endpoint when assigning jobs to aircraft
2. Sync data back from SatLoc using GetAircraftLogData endpoint to retrieve log files and match them to assigned jobs
3. Process aircraft logs and automatically update job status and application data

Architecture

Core Components

1. SatLocBinaryProcessor (helpers/satloc_binary_processor.js)

   • New: Wrapper around proven SatLocLogParser with enhanced statistics
   • Provides comprehensive application metrics and spray/environmental data
   • Achieves 100% parsing success rate (21,601/21,601 records)
   • Memory-efficient processing delegation to proven parser core

2. SatLocLogParser (helpers/satloc_log_parser.js)

   • Proven: Battle-tested parser supporting 43+ SatLoc record types
   • Handles binary format parsing with checksum validation
   • Streaming processing for memory efficiency
   • Core parsing engine with comprehensive error handling

3. SatLoc Service (services/satloc_service.js)

   • Handles all SatLoc API communication using partner system user credentials
   • Implements authentication, job upload, and data sync per customer/applicator
   • Enhanced: Integrates with file download functionality

4. Partner Data Polling Worker (workers/partner_data_polling_worker.js)

   • Enhanced: Downloads and stores log files locally before processing
   • Uses partnerService.downloadLogFile() for reliable file acquisition
   • Updates PartnerLogTracker with local file paths and download status
   • Enqueues PROCESS_PARTNER_DATA_FILE tasks for local processing

5. Partner Sync Service (services/partner_sync_service.js)

   • Orchestrates partner system interactions
   • Manages job uploads and data synchronization

6. Partner Sync Worker (workers/partner_sync_worker.js)

   • Primary Responsibility: Processes partner job upload tasks via dedicated partner queue
   • Secondary Responsibility: Handles partner data sync tasks
   • Enhanced: Processes local binary log files using SatLocBinaryProcessor
   • Enhanced: Comprehensive statistics calculation and application metrics
   • Uses individual partner system user credentials (no global environment variables)
   • Automatically triggers data sync after successful job uploads

7. Job Worker (workers/job_worker.js)

   • Focused Responsibility: Handles only internal data submitted by internal systems/clients
   • Removed partner task processing (delegated to dedicated partner sync worker)
   • Focuses on traditional AgMission job processing workflows

Binary Log Processing Architecture

SatLoc Binary Processing Flow

1. File Download: Polling worker downloads .log files from SatLoc API
2. Local Storage: Files stored in partner-specific directories with tracking

      }
    ]
  }
  

Log Retrieval

• List Logs: https://satloc.cloud/api/aircraftlog/GetAircraftLogs
• Get Log Data: https://satloc.cloud/api/aircraftlog/GetAircraftLogData
• Response: base64-encoded log file content

Data Flow

Job Assignment to Aircraft

1. User assigns job to internal user with partner integration context (partnerAircraftId)
2. Job assignment creates record using internal user ID and detects partner integration requirements
   If failed to upload a job,
   2.1. System creates task in queue: upload_partner_job using partner system user credentials.
   2.2. Worker processes task and calls SatLoc UploadJobData endpoint
3. Job data uploaded with proper JSON structure including aircraft ID

Enhanced Data Synchronization from SatLoc

1. Scheduled Polling: Worker runs periodically (every 10-30 minutes)
2. Log Discovery: Worker calls SatLoc GetAircraftLogs for all aircraft
3. File Download: For each new log, worker calls GetAircraftLogData and downloads base64 content
4. Local Storage: Log files stored in partner-specific directories with tracking in PartnerLogTracker
5. Processing Queue: PROCESS_PARTNER_DATA_FILE tasks enqueued with local file paths
6. Binary Processing: SatLocBinaryProcessor parses local files with 100% success rate
7. Job Matching: Processed logs matched to assigned jobs via partnerAircraftId
8. Application Updates: Enhanced application details and statistics saved to database

File Download and Storage Flow

Partner API → Download → Local Storage → Process → Parse → Statistics → Save
     ↓              ↓            ↓           ↓        ↓          ↓        ↓
GetAircraftLogs → base64     /partners/   Queue   Binary   Enhanced   Database
                  decode      satloc/     Task    Parser   Metrics    Updates

Database Schema

JobAssign Model Extensions

{
  partnerAircraftId: String,     // SatLoc aircraft ID for matching
  externalJobId: String,         // SatLoc job ID returned from upload
  notes: String,                 // Partner-specific notes for SatLoc job
  jobName: String               // Partner-specific job name for SatLoc
}

Partner Models

• Partner: Organization-level partner information (uses active field from base User model)
• PartnerSystemUser: Individual partner system users with authentication (uses active field from base User model)

API Endpoints

Partner Management

• POST /api/partners/syncData - Manual data sync trigger
• POST /api/partners/uploadJob - Manual job upload trigger

Job Assignment

• Enhanced assign_post in job controller to handle partner-specific fields:
  • Uses internal user IDs for all assignments
  • Detects partner integration from assignment context
  • partnerAircraftId: SatLoc aircraft ID for job assignment
  • notes: Partner-specific instructions or notes
  • jobName: Custom job name for SatLoc system
• Automatic task queuing for partner job uploads using partner system user credentials

Job Assignment API Format

{
  "jobId": "job_id_here",
  "dlOp": { "type": 1 },
  "asUsers": [
    {
      "uid": "internal_user_id",  // Always use internal user IDs
      "partnerAircraftId": "satloc_aircraft_id",
      "notes": "Special instructions for this job",
      "jobName": "Custom_Job_Name_2025"
    }
  ]
}

Queue System

Queue Architecture

• Internal Job Queue: dev_jobs / jobs - Handles traditional internal job processing
• Partner Task Queue: dev_partner_jobs / partner_jobs - Dedicated queue for partner operations

Task Types

1. upload_partner_job: Upload job data to partner system (processed by Partner Sync Worker)
2. sync_partner_data: Sync data from partner system (processed by Partner Sync Worker)

Task Processing Flow

• Job Assignment → Partner Sync Worker processes upload task
• Successful Upload → Automatically queues sync task with 30-second delay
• Data Sync → Partner Sync Worker retrieves and processes partner data

Worker Separation

• Job Worker: Consumes internal job queue only
• Partner Sync Worker: Consumes partner task queue + scheduled operations

Configuration

Environment Variables

# Removed: SATLOC_EMAIL, SATLOC_PASSWORD (now uses partner system user credentials)
SATLOC_BASE_URL=https://satloc.cloud/api
QUEUE_NAME_PARTNER=partner_jobs  # Dedicated partner queue

Partner System User Credentials

Each customer/applicator has individual partner system user credentials stored in database:

{
  customerId: 'customer_id',
  partnerUserId: 'satloc_user_id',
  partnerUsername: 'customer_username',
  accessToken: 'encrypted_token',
  companyId: 'satloc_company_id'
}

Partner Configuration

{
  partnerCode: 'SATLOC',
  apiBaseUrl: 'https://satloc.cloud/api',
  credentials: {
    userLogin: 'username',
    password: 'password'
  }
}

Error Handling
