  • Weight: With a weight of 2,232 kg, it is the heaviest satellite in the constellation.
  • Navigation Payloads: NVS-01 carries navigation payloads in L1, L5, and S bands.
  • Purpose: The satellite aims to provide continuity for NavIC services, the Indian Regional Navigation Satellite System, which offers accurate and real-time navigation within India and a 1,500 km region around the country.
  • First-generation Comparison: In contrast to the first-generation NavIC satellites, NVS-01 is much heavier, weighing around 1,425 kg at liftoff.
Rubidium Atomic Clock:
  • NVS-01 incorporates a Rubidium atomic clock, a significant technological advancement developed by India.
  • Some existing satellites in the navigation constellation faced accuracy issues due to failed atomic clocks.
  • NVS-01 aims to rectify this problem by ensuring precise time measurements for accurate location information.
Signal Frequencies:
  • In addition to the L5 and S frequency signals provided by existing satellites, NVS-01 will also transmit signals in the L1 frequency.
  • This enhances interoperability with other satellite-based navigation systems.
  • The L1 frequency, widely used in the Global Positioning System (GPS), facilitates the use of regional navigation systems in wearable devices and personal trackers with low-power, single-frequency chips.
Extended Mission Life:
  • NVS-01 is designed for a longer mission life of over 12 years, surpassing the 10-year mission life of existing satellites.

What is NavIC?

  • NavIC, or Navigation with Indian Constellation, is an independent stand-alone navigation satellite system developed by the Indian Space Research Organisation.
  • NavIC was originally approved in 2006 at a cost of $174 million. It was expected to be completed by late 2011, but only became operational in 2018.
  • NavIC consists of eight satellites and covers the whole of India’s landmass and up to 1,500 km (930 miles) from its boundaries.
  • Currently, NavIC’s use is limited. It is being used in public vehicle tracking in India, for providing emergency warning alerts to fishermen venturing into the deep sea where there is no terrestrial network connectivity, and for tracking and providing information related to natural disasters.
How does NavIC compare?
  • The main difference is the serviceable area covered by these systems.
  • GPS caters to users across the globe and its satellites circle the earth twice a day, while NavIC is currently for use in India and adjacent areas.
  • Like GPS, there are three more navigation systems that have global coverage –
    • Galileo from the European Union,
    • Russia-owned GLONASS
    • China’s Beidou
  • QZSS, operated by Japan, is another regional navigation system covering Asia-Oceania region, with a focus on Japan.
  • India’s 2021 satellite navigation draft policy stated the government will work towards “expanding the coverage from regional to global” to ensure availability of NavIC signal in any part of the world.

National Rare Diseases Committee


Recently, the Delhi High Court has taken a proactive step to address the challenges faced by patients with rare diseases by establishing a five-member panel to implement the Centre’s rare diseases policy effectively.

  • The panel, known as the National Rare Diseases Committee, aims to ensure that patients enrolled with the All-India Institute of Medical Sciences (AIIMS), Delhi, receive timely treatment and benefit from the policy.


GS II: Government Policies and Interventions

Dimensions of the Article:

  1. What are ‘Rare diseases’?

  3. National Rare Diseases Committee
  4. Provisions of the National Rare Disease Policy 2021

What are ‘Rare diseases’?

A rare disease, also referred to as an orphan disease, is any disease that affects a small percentage of the population.

Most rare diseases are genetic, and are present throughout a person’s entire life, even if symptoms do not immediately appear.

  • Haemophilia,
  • Thalassemia,
  • Sickle-cell anaemia,
  • Auto-immune diseases,
  • Pompe disease,
  • Hirschsprung disease,
  • Gaucher’s disease,
  • Cystic Fibrosis,
  • Hemangiomas and
  • Certain forms of muscular dystrophies

Are some of the most common rare diseases recorded in India.

Pressing Issues regarding ‘Rare diseases’

  • Rare diseases pose a significant challenge to health care systems because of the difficulty in collecting epidemiological data, which in turn impedes the process of arriving at a disease burden, calculating cost estimations and making correct and timely diagnoses, among other problems.
  • There are 7,000-8,000 classified rare diseases, but less than 5% have therapies available to treat them.
  • About 95% rare diseases have no approved treatment and less than 1 in 10 patients receive disease-specific treatment. Where drugs are available, they are prohibitively expensive, placing immense strain on resources.
  • These diseases have differing definitions in various countries and range from those that are prevalent in 1 in 10,000 of the population to 6 per 10,000.
  • India has said it lacks epidemiological data on the prevalence here and hence has only classified certain diseases as ‘rare.’
  • Currently, only a few pharmaceutical companies are manufacturing drugs for rare diseases globally and there are no domestic manufacturers in India except for those who make medical-grade food for those with metabolic disorders.
  • Due to the high cost of most therapies, the government has not been able to provide these for free.

National Rare Diseases Committee:

The National Rare Diseases Committee is a panel established by the Delhi High Court to address the challenges faced by patients with rare diseases and implement the rare diseases policy.


The committee is composed of five members who are experts in relevant fields, including medical professionals, policymakers, and representatives from healthcare institutions.

Responsibilities and Objectives:

Assessing Cases:

  • The committee focuses on patients enrolled with AIIMS in Delhi.
  • It evaluates individual cases to understand the medical needs of patients with rare diseases and determine appropriate treatment options.

Implementation of the Policy:

  • The committee devises strategies and guidelines for translating the provisions of the rare diseases policy into actionable steps.
  • It ensures that the policy is effectively implemented to benefit patients with rare diseases.

Coordination and Collaboration:

  • The committee facilitates close coordination between the medical community, therapy providers, and governmental agencies.
  • It creates a collaborative environment to address the challenges associated with rare diseases and find collective solutions.

Treatment Accessibility:

  • One of the committee’s objectives is to ensure timely access to treatment for patients with rare diseases.
  • It explores avenues for procuring necessary therapies and drugs and establishes a logistical framework for the seamless administration of treatment.

Provisions of the National Rare Disease Policy 2021

  • Patients of rare diseases will be eligible for a one-tome treatment under the Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (AB-PMJAY).
  • Financial support up to Rs20 lakh under the Umbrella Scheme of Rashtriya Arogaya Nidhi shall be provided by the central government for treatment of those rare diseases that require a one-time treatment (diseases listed under Group 1) for their treatment in Government tertiary hospitals only. – (NOT be limited to below poverty line (BPL) families, but extended to about 40% of the population as eligible under the norms of Pradhan Mantri Jan Arogya Yojana (PMJAY))
The policy has categorised rare diseases in three groups:
  • Disorders amenable to one-time curative treatment;
  • Those requiring long term or lifelong treatment; and
  • Diseases for which definitive treatment is available but challenges are to make optimal patient selection for benefit.

The government has said that it will also assist in voluntary crowd-funding for treatment as it will be difficult to fully finance treatment of high-cost rare diseases.

Criticisms of the National Rare Disease Policy 2021
  • Though the document specifies increasing the government support for treating patients with a ‘rare disease’— from Rs 15 lakh to Rs 20 lakh — caregivers say this doesn’t reflect actual costs of treatment.
  • The Policy leaves patients with Group 3 rare diseases to fend for themselves due to the absence of a sustainable funding support.
  • What the policy doesn’t capture is that these are diseases that last a lifetime adding up to a huge amount of expenditure and many of the patients who can’t afford such treatment will be unable to even make it to the prescribed tertiary hospitals for treatment.
