gridgs-sdk 1.1.1

Python SDK to simplify integration with GRID services

GRID Python SDK

A Python SDK to simplify integration with GRID services.

Website: https://gridgs.com
PyPI: https://pypi.org/project/gridgs-sdk/

Installation

pip install gridgs-sdk

Note: This SDK is currently in beta. Please expect potential changes (we'll try to maintain backward compatibility where possible).

Main Components

• GridAuthClient (gridgs.sdk.auth.Client) - Handles authorization with GRID SSO server
• GridApiClient (gridgs.sdk.api.Client) - Client for GRID REST API to work with main GRID entities
• GridEventSubscriber (gridgs.sdk.event.Subscriber) - Subscriber to receive real-time events about session changes (creation, deletion, starting, etc.)
• GridMQTTClient (gridgs.sdk.mqtt.Client) - Client for GRID MQTT API, useful for real-time communication (receiving downlink frames and sending uplink frames)

Usage Examples

GridAuthClient

from keycloak import KeycloakOpenID
from gridgs.sdk.auth import Client as GridAuthClient

keycloak_openid = KeycloakOpenID(
    server_url="https://login.gridgs.com", 
    client_id="grid-api", 
    realm_name="grid"
)
grid_auth_client = GridAuthClient(
    open_id_client=keycloak_openid, 
    username="[e-mail]", 
    password="userpass", 
    logger=logging.getLogger('grid_auth_client')
)

GridApiClient

from gridgs.sdk.api import Client as GridApiClient

grid_api_client = GridApiClient(
    base_url="https://api.gridgs.com",
    auth_client=grid_auth_client, 
    logger=logging.getLogger('grid_api_client')
)

Get Sessions

from gridgs.sdk.api import SortOrder, SessionQueryParams, SessionSortField

params = SessionQueryParams(
    satellite=1,
    ground_station=13,
    status=Session.STATUS_SUCCESS,
    offset=0, 
    limit=3, 
    sort_by=SessionSortField.END_DATE, 
    sort_order=SortOrder.ASC
)
sessions_result = grid_api_client.find_sessions(params)

print(f'Total: {sessions_result.total}')

Iterate All Sessions

Iterates through all sessions in chunks (default chunk size: 500) based on query parameters.

from gridgs.sdk.api import SortOrder, SessionQueryParams, SessionSortField

params = SessionQueryParams(
    offset=0, 
    limit=1000000,
    satellite=1,
    ground_station=13,
    status=Session.STATUS_SUCCESS,
    sort_by=SessionSortField.END_DATE, 
    sort_order=SortOrder.ASC
)

for session in grid_api_client.iterate_sessions(params):
    print(session)

Get Session by ID

session = grid_api_client.find_session(session_uuid)

Predict Sessions

Maximum: 100 sessions

from gridgs.sdk.api import NonPaginatedSessionQueryParams

params = NonPaginatedSessionQueryParams(
    satellite=1, 
    ground_station=13,
    date_from=datetime.fromisoformat("2025-01-01 00:00:00"),
    date_to=datetime.fromisoformat("2025-01-02 00:00:00"),
    min_tca_elevation=20,
)
sessions = grid_api_client.predict_sessions(params)

Create Session

session = Session()  # A session from get_predicted_sessions
session = grid_api_client.create_session(session)

Delete Session

grid_api_client.delete_session(session_uuid)

Get Frames

from gridgs.sdk.api import SortOrder, FrameSortField, FrameQueryParams

params = FrameQueryParams(
    satellite=2, 
    ground_station=13, 
    date_from=datetime.fromisoformat("2025-02-07 00:00:00"), 
    date_to=datetime.fromisoformat("2025-02-07 00:48:00"), 
    offset=0, 
    limit=5, 
    sort_by=FrameSortField.CREATED_AT, 
    sort_order=SortOrder.ASC
)

frames_result = grid_api_client.find_frames(params)
print(f'Total: {frames_result.total}')

Iterate All Frames

Iterates through all frames in chunks (default chunk size: 500) based on query parameters.

from gridgs.sdk.api import SortOrder, FrameSortField, FrameQueryParams

params = FrameQueryParams(
    offset=0, 
    limit=1000000, 
    satellite=1,
    ground_station=13,
    date_from=datetime.fromisoformat("2025-02-07 00:00:00"), 
    date_to=datetime.fromisoformat("2025-02-07 00:48:00"), 
    sort_by=FrameSortField.CREATED_AT, 
    sort_order=SortOrder.ASC
)

for frame in grid_api_client.iterate_frames(params):
    print(frame)

SSL/TLS Configuration

For GridEventSubscriber and GridMQTTClient:

from gridgs.sdk.ssl import Settings as SslSettings

ssl_settings = SslSettings(version=ssl.PROTOCOL_TLSv1_2, verify=True)

Note: When using SSL/TLS settings, use port 8883. Arguments have default values.

GridEventSubscriber

Receive session status events for satellite:

from gridgs.sdk.entity import SessionEvent
from gridgs.sdk.event import Subscriber as GridEventSubscriber

grid_event_subscriber = GridEventSubscriber(
    host="api.gridgs.com", 
    port=1883, 
    auth_client=grid_auth_client,
    satellite_id=2,
    ssl_settings=None, 
    logger=logging.getLogger('grid_event_subscriber')
)

def on_event(event: SessionEvent):
    session = event.session
    event_type = event.type  # Create, Update, Delete

grid_event_subscriber.on_event(on_event)
grid_event_subscriber.run()

GridMQTTClient

from gridgs.sdk.entity import Frame
from gridgs.sdk.mqtt import Client as GridMQTTClient

grid_mqtt_client = GridMQTTClient(
    host="api.gridgs.com", 
    port=1883, 
    auth_client=grid_auth_client, 
    ssl_settings=None, 
    logger=logging.getLogger('grid_mqtt_client')
)

def on_downlink_frame(frame: Frame):
    pass

grid_mqtt_client.on_downlink(on_downlink_frame)
grid_mqtt_client.connect(session)

Sending a Frame

grid_mqtt_client.send(b'Uplink frame data')
